BACKGROUND OF THE INVENTION

[0002] Marathon training requires consistent physical conditioning, endurance building, and adaptation to varying terrain and weather conditions. Many runners follow structured training programs to prepare for competitive events, which include long-distance running sessions, tracking of physiological parameters, and adapting to environmental factors similar to real marathon settings. Maintaining discipline, safety, and performance monitoring throughout such training is crucial for both professional and amateur athletes.

[0003] Traditionally, runners train outdoors on roads, tracks, or natural trails to simulate actual race conditions. They rely on personal fitness system, smartphones, or manual logs to track performance. However, outdoor training is often affected by unpredictable weather, traffic, surface conditions, and time-of-day limitations. These factors can disrupt the consistency of training, pose safety risks, and reduce training efficiency. Some individuals use indoor treadmills for convenience, but standard treadmills provide limited features and fail to simulate real-world terrain or environmental changes. Additionally, users must manually input or track data, which increases the risk of inaccurate readings or ineffective training.

[0024] Figure 1 further illustrates an LED (Light Emitting Diode) 105b light connected via a ball-and-socket joint 105c, a wearable band 106 integrated with the system and embedded with a sensing module 107, a holographic projection unit 108 installed within the housing 101, a plurality of air holes 109 distributed across the housing 101, each air hole equipped with a motorized iris lid 110, a high-pressure oxygen cylinder 111 with a regulated flow valve 112 is integrated within the housing 101.

[0025] The present invention includes a housing 101 having an entrance fitted with a hinged door 102 for user access. The housing 101, according to the invention, is a structurally enclosed unit designed to provide a secure, private, and immersive in door 102 training space. The hinged door 102 for easy user access and is constructed to maintain controlled internal conditions, ensuring isolation from external disturbances and supporting a consistent and customizable training environment.

[0026] The enclosed structure of the housing 101 is designed to create a safe and controlled space for indoor marathon training. The housing 101 is made using insulated panels, which have a thick foam layer in the middle and hard outer layers made of fiberglass. This helps keep the inside quiet and at a steady temperature. Strong metal frames are used at the corners to hold everything firmly in place. The panels are sealed tightly with rubber linings to stop air or moisture from getting in. Ventilation slots are included in the housing 101 walls to ensure proper airflow inside, keeping the environment fresh and comfortable during training sessions. The floor is reinforced to carry the weight of the user and equipment.

[0027] The hinged door 102 mentioned herein is a manually operable swing-type door 102 mounted on the housing 101 using heavy-duty butt hinges fixed along one vertical edge. These hinges consist of interlocking metal plates (leaves) connected by a central pin, allowing the door 102 to pivot around a fixed axis. When the user pushes or pulls the door 102, the rotational motion is facilitated by the hinge pin, enabling smooth angular displacement up to 180 degrees or 90 degrees. A mechanical latch or handle secures the door 102 in the closed position. The latch consists of a spring-loaded bolt that fits into a strike plate on the door 102 frame. When the user operates a handle that is attached with door 102, the latch retracts, allowing the door 102 to open, releasing the handle engages the latch automatically, ensuring closure.

[0028] In an embodiment of the present invention a user is required to access and presses a push button arranged on the housing 101 to activate the system for associated processes of the system. The push button when pressed by the user, closes an electrical circuit and allows currents to flow for powering an associated microcontroller of the system for operating of all the linked components for performing their respective functions upon actuation. The microcontroller, mentioned herein, is preferably an Arduino microcontroller. The Arduino microcontroller used herein controls the overall functionality of the linked components.

[0029] An imaging unit 114 combined with an infrared proximity sensor is mounted above the entrance to detect and capture the user's presence and facial features, enabling identity authentication and allowing entry only after successful verification. The imaging unit 114 integrates a camera and a processor encrypted with an artificial intelligence protocol, working together to capture and process multiple images of the user for detecting user’s identity. Upon actuation, the camera captures images which are then fed to the processor. The AI protocol operates by following predefined instructions to autonomously analyze and interpret the captured data to determine user’s identity. Initially, data is collected and stored in a database, enabling the artificial intelligence to learn and improve its understanding through iterative training. This continuous learning allows the protocol to refine its decision-making capabilities over time, optimizing performance in detecting user’s identity. The protocol periodically undergoes evaluation and updates to maintain accuracy and effectiveness, ensuring reliable analysis of the images captured by the imaging unit 114.

[0030] The infrared proximity sensor mentioned herein functions by emitting a beam of infrared light through an IR LED. When a human body, comes within its detection range, the infrared light reflects off the object’s surface and is captured by a photodiode or phototransistor within the sensor. The sensor measures the intensity and angle of the reflected light to calculate the distance of the object from the sensor. Based on the signal strength and time-of-flight of the infrared beam, the sensor determines if the user is within the predefined proximity range. The microcontroller combines this proximity data with input from the imaging unit 114 to accurately detect user presence permitting entry after successful verification.

[0031] A user interface is installed in a computing unit linked with a microcontroller inbuilt in the system to wirelessly connect system with computing unit by means of a communication module. The user interface enables the user to provide personal and medical information as input into a user-profile created in a database, and specify training levels and preferences for customized running practice sessions. The system preferably uses a relational database such as MySQL or PostgreSQL, which organizes data into structured tables linked by defined relationships. This format allows efficient querying, updating, and management of user information, including personal details, medical history, training levels, and performance metrics. Relational databases ensure data integrity, scalability, and easy integration with the computing unit, making them ideal for handling structured user data in personalized training applications.

[0032] The communication module includes, but not limited to Wi-Fi (Wireless Fidelity) module, Bluetooth module, GSM (Global System for Mobile Communication) module. The communication module used in the system is
preferably the Wi-Fi module. The Wi-Fi module enables wireless communication by transmitting and receiving data over radio frequencies using IEEE 802.11
protocols. It connects to a network via an access point, converting digital
data into radio signals. The module processes TCP/IP protocols for data
exchange, interfaces with microcontrollers through UART/SPI, and ensures
encrypted communication using WPA/WPA2 security standards for secure and
efficient wireless connectivity

[0033] For example, the relational database includes a table named User Profile containing fields like User ID, Name, Age, Medical Conditions, and Preferred Training Level. Another linked table, Performance logs, stores data such as Session date, Distance run, Heartrate, and Hydration status. These tables are connected using User ID, allowing the user to progress and personalize training based on each user’s health and performance data.

[0034] A treadmill arrangement 103 is installed on a platform 104 inside the housing 101 to simulate dynamic real-world terrain variations with high fidelity during indoor 102 marathon training. The treadmill arrangement 103 is mounted on a multi-axis motion unit 103b includes a spherical actuators 103c equipped with rotary joints 103d and Inertial Measurement Units (IMUs), enabling the treadmill 103a to tilt and shift in multiple directions in real time. The microcontroller processes the input commands received from the user interface whether preloaded training programs or real-time user adjustments and based on this command actuates the spherical actuators 103c, which are capable of producing rotational movement along multiple axes from a single point, using a ball-and-socket joint 105c.

[0035] Each actuator consists of a spherical core housed within a motorized shell,
where embedded servo motors drive the core in pitch, roll, and yaw directions
independently or simultaneously to precise orientation adjustments. They are
connected via rotary joints 103d, which provide controlled angular rotation about
specific axes pitch (forward/backward tilt), roll (side-to-side tilt), and yaw
(horizontal rotation). Each joint consists of a shaft connected to a servo
motor along with bearings that allow smooth rotation and support axial loads.

[0036] These motors apply torque to rotate the joint to a specific angle for accurate motion control. The coordinated movement of multiple rotary joints 103d enables compound motions, allowing the treadmill 103a to tilt or shift laterally to simulate complex terrain surfaces. The IMUs includes accelerometers, gyroscopes and magnetometers are mounted on the treadmill 103a platform 104 to measure current orientation, acceleration and angular velocity in real time.

[0037] The accelerometer mentioned herein operates using a micro-electromechanical arrangement comprising a small mass suspended by springs inside a silicon structure. When the sensor experiences motion, the mass shifts causing a change in capacitance between fixed and moving electrodes. This change is converted into an electrical signal proportional to the acceleration. The signal is processed to determine direction and magnitude of movement.

[0038] The magnetometers mentioned herein works on the Hall effect principle, where a thin conductive material carries an electric current while exposed to a magnetic field perpendicular to the current flow. This magnetic field exerts a Lorentz force on the moving charge carriers, causing them to accumulate on one side of the material and creating a voltage difference known as the Hall voltage across the material perpendicular to both the current and magnetic field. This Hall voltage is directly proportional to the strength of the magnetic field, allowing precise measurement of magnitude and direction.

[0039] An array of sensors integrated with the treadmill 103a arrangement 103 to monitor user form and stability. The array of sensors incudes a load sensor to measure vertical force applied by the user's feet during each step, a combination of gyroscope and accelerometer combination for monitoring gait cycle, balance, and angular orientation of the user.

[0040] The load sensor, mentioned herein a strain gauge or force-sensitive resistor (FSR), is embedded beneath the treadmill 103a belt to measure vertical ground reaction force exerted by the user's foot during each step. As the user runs or walks, the sensor deforms slightly under pressure, generating a variable electrical signal proportional to the applied load. This signal is processed by an analog-to-digital converter and relayed to the microcontroller for analysis. Real-time data on step force and foot strike patterns help in evaluating user form, identifying asymmetries, and preventing injuries by ensuring balanced foot loading and proper biomechanics during training.

[0041] The inertial measurement unit (IMU), comprising a gyroscope and accelerometer, is positioned within the treadmill 103a platform 104 or wearable to monitor gait cycle, angular orientation, and dynamic stability. The accelerometer measures linear acceleration in three axes, capturing motion, step timing, and stride length, while the gyroscope tracks rotational movement to assess body orientation and balance. Together, they generate real-time motion data transmitted to the microcontroller interpret this information to detect irregularities, posture deviations, or instability, allowing for adaptive feedback or treadmill 103a adjustment to maintain proper form and optimize user performance throughout the marathon training session. The microcontroller operatively linked with the sensors, configured to dynamically adjust treadmill 103a movement in real time based on sensor feedback.

[0042] The sensor includes amplification and signal conditioning circuits to convert the Hall voltage into a usable electrical signal and then transmits to the microcontroller for correcting drift in accelerometer and gyroscope readings. Magnetometers improve orientation accuracy by providing heading information, helping maintain proper alignment and dynamically assisting in adjusting the actuators 103c to match the desired terrain profile.

[0043] A weather adjustment module 105 positioned within the housing 101, configured to replicate race-day environmental conditions by simulating variations in temperature, wind, and lighting. This allows users to better prepare and adapt their performance under different weather scenarios.

[0044] The weather adjustment module 105 includes a variable-speed fan 105a positioned at a front portion of the housing 101 and coupled with a flow sensor to blow air toward the user. The fan 105a is actuated by the microcontroller using a PWM (Pulse Width Modulation) signal to regulate the voltage supplied to the fan’s DC motor. Based on environmental simulation requirements, the microcontroller adjusts the duty cycle of the PWM to control the rotation speed of the blades. Higher speed generates stronger airflow toward the user to mimic windy conditions, while lower speed simulates milder air movement. The fan 105a deliver targeted airflow, contributing to a more immersive and realistic marathon training experience by simulating external wind conditions encountered during actual races.

[0045] The flow sensor operates by detecting the rate of airflow generated by the fan 105a, commonly using thermal anemometry or pressure-based sensing principles. As air passes through the sensor, it alters the thermal or pressure profile within the sensor chamber. These variations are converted into electrical signals proportional to the flow rate. The data is sent to the microcontroller, which continuously evaluates airflow intensity and makes necessary real-time adjustments to the fan 105a speed to maintain desired simulation levels. This closed-loop control ensures consistent and accurate environmental feedback during indoor 102 training sessions.

[0046] An LED (Light Emitting Diode) 105b light connected via a ball-and-socket joint 105c to adjust light direction and intensity dynamically to simulate natural sunlight patterns. The LED 105b light is controlled by the microcontroller that regulates its intensity through Pulse Width Modulation (PWM). The microcontroller adjusts the duty cycle of the PWM signal to increase or decrease brightness, simulating various natural sunlight conditions like dawn, midday, or dusk. Color temperature can also be modulated using multi-color LED 105b arrays. The LED 105b emits light when forward-biased voltage is applied, causing electrons to recombine with holes 109 and release photons. The microcontroller allows for real-time dynamic lighting changes based on environmental simulation inputs or user training requirements.

[0047] The LED 105b light is physically mounted on the ball-and-socket joint 105c that provides a wide range of angular motion. This mechanical joint allows the LED 105b to be tilted or rotated in multiple directions without detachment, enabling the direction of light to be manually or motor-actuated. The joint’s spherical design fits within a socket, allowing smooth pivoting and stable positioning. This flexibility enables dynamic adjustment of lighting angles to replicate shifting sunlight directions, enhancing the realism of the training environment inside the housing 101.

[0048] A Peltier unit synced with an integrated temperature sensor configured to provide both heating and cooling. The Peltier unit, also known as a thermoelectric cooler, operates on the Peltier effect, where heat is absorbed or released at the junction of two different conductors when an electric current passes through them. When powered by the microcontroller, one side of the unit becomes hot while the opposite side becomes cold, allowing to either heat or cool the surrounding air inside the housing 101. The direction of the current determines the thermal direction, enabling dynamic temperature regulation. The Peltier unit is used to simulate race-day temperature variations during marathon training.

[0049] The temperature sensor continuously monitors the ambient air temperature inside the housing 101 and relays real-time data to the microcontroller. The temperature sensor preferably a thermistor, which changes its resistance or output signal with temperature fluctuations. This signal is processed by the microcontroller to determine whether to activate the Peltier unit for heating or cooling. The sensor ensures precise climate control by enabling responsive thermal management, ensuring that the environment remains within the desired range set for the user’s customized training conditions.

[0050] A plurality of air holes 109 are arranged throughout the housing 101, with each air hole fitted with a motorized iris lid 110 that functions as an adjustable opening to regulate the amount of airflow, thereby maintaining proper ventilation and ensuring a comfortable environment for indoor 102 marathon training. The iris lid 110 is an adjusting circular aperture comprised of an actuation ring and a plurality of blades according to the size of the lid 110. The blades are engraved with the protrusions through which the actuation ring is affixed to each blade.

[0051] The actuation ring is connected to a motor, which helps in the movement of the actuation ring leading to the movement of blades inward or outward to change the size of the opening. When the blades close, the aperture becomes smaller, closing the lid 110. When the blades open, the aperture widens, opening the lid 110. This adjustment allows the iris lid 110 to control the amount of airflow, thereby maintaining proper ventilation and ensuring a comfortable environment for indoor 102 marathon training.

[0052] The weather adjustment module 105 is functionally connected to a GPS module 105 that monitors the user’s virtual position along a preset marathon route, and is designed to access location-based environmental data through a built-in internet-enabled weather forecasting module 105, thereby allowing the system to realistically simulate race-day weather conditions based on the user’s virtual location.

[0053] The GPS (Global Positioning System) module functions by receiving time-stamped radio signals from a constellation of satellites orbiting the Earth. By calculating the time delay between transmission and reception of signals from at least four satellites, the module triangulates the user’s exact virtual location along a predefined marathon route. The module is continuously synchronized with the training system to simulate movement across various terrains in real time. It updates location coordinates dynamically, allowing the system to adjust training parameters accordingly. The GPS module ensures that environmental simulation is based on geographically accurate data, enhancing the realism of the virtual course.

[0054] The weather forecasting module is an internet-enabled unit configured to retrieve real-time meteorological data corresponding to the user’s GPS location. The module interfaces with cloud-based weather APIs or remote data servers to gather information such as temperature, humidity, wind speed, UV index, and light intensity. This data is relayed to the training system’s microcontroller for processing. Based on this input, the environmental simulation elements inside the housing 101 are adjusted to match real-world weather conditions. The module ensures timely updates and is capable of predictive adjustments by analyzing weather patterns, enabling the microcontroller to emulate race-day environments with high accuracy and responsiveness.

[0055] The weather adjustment module 105 is an electromechanical unit integrated within the housing 101 to recreate realistic environmental conditions in door 102s. Based on input from the GPS and weather forecasting modules, it regulates airflow, temperature, humidity, and lighting to match the virtual location’s conditions. For example, the fan 105a simulates wind, the Peltier unit manages temperature variations, and the LED105b mimic natural lighting patterns. This module 105 ensures a multisensory training experience by adjusting the indoor 102 environments in real time, improving realism and athlete adaptation.

[0056] For example, the user selects the Boston Marathon route using the interface. The GPS module simulates their virtual position along this course, while the weather forecasting module retrieves real-time Boston weather data like temperature, wind, and sunlight. Based on this, the weather adjustment module activates fan 105a to simulate wind, adjusts the Peltier unit to match the outdoor 102 temperatures, and sets the LED 105b lighting to mimic the time-of-day conditions for a realistic training experience.

[0057] A display screen 113 integrated within the housing 101 providing real-time performance metrics and immersive, interactive visualizations of marathon courses. The display screen 113 touch interactive display panel as mentioned herein is an LCD (Liquid Crystal Display) screen 113 that presents output in a visible form. The screen 113 is equipped with touch-sensitive technology, allowing the user to interact directly with the display using their fingers. A touch controller IC (Integrated Circuit) is responsible for processing the analog signals providing real-time performance metrics and immersive, interactive visualizations of marathon courses. The touch controller is connected to the microcontroller through various interfaces which may include but are not limited to SPI (Serial Peripheral Interface) or I2C (Inter-Integrated Circuit).

[0058] A wearable band 106 incorporated into the system and embedded with a sensing module 107 configured to continuously monitor the user's real-time physiological parameters, the microcontroller dynamically modifies workout intensity and environmental conditions to ensure optimal safety and enhance performance. The sensing module 107 includes an optical heart rate sensor, a pulse oximeter sensor, a skin temperature sensor, and an Inertial Measurement Unit (IMU).

[0059] The wearable band 106 used in the system is a flexible, lightweight smart band 106 is made from skin-friendly materials such as silicone or thermoplastic polyurethane (TPU). These materials ensure comfort, breathability, and durability during prolonged use, especially in high-sweat conditions. The band 106 is designed with an adjustable strap to provide a secure fit around the user’s wrist. The band 106 is moisture-resistant, hypoallergenic, and suitable for continuous physiological monitoring.

[0060] The optical heart rate sensor uses photo plethysmography (PPG) to detect blood volume changes in the microvascular bed of tissue. The sensor consists of light-emitting diodes (green LEDs) that project light into the skin and photodetectors that measure the amount of light either absorbed or reflected. As the heart pumps blood, the volume of blood in the vessels changes, causing variations in light absorption. These variations are detected and converted into an electrical signal, which is processed to calculate the user’s heart rate. The sensor continuously transmits data to the microcontroller for real-time heart rate monitoring and training adjustments.

[0061] The pulse oximeter sensor works by emitting two wavelengths of light red and infrared through the skin to measure the oxygen saturation level (Spot₂) in the blood. The sensor detects the difference in absorption of these lights by oxygenated and deoxygenated hemoglobin. A photodiode captures the transmitted or reflected light, and the ratio of absorbed red to infrared light is used to calculate blood oxygen levels. The pulse oximeter also detects pulse rate by monitoring changes in light absorption due to blood flow. The microcontroller processes this data to ensure adequate oxygen levels are maintained during physical activity.

[0062] The skin temperature sensor mentioned herein a thermistor measures the surface temperature of the skin by detecting thermal radiation or resistance changes due to temperature. When in contact with the user’s skin, the sensor generates a voltage signal corresponding to the temperature. This analog signal is then converted to a digital signal and transmitted to the microcontroller. Continuous monitoring helps detect abnormal temperature rise or fall, indicating potential fatigue, overheating, or illness. The microcontroller uses this data to adjust the training conditions or alert the user, ensuring safe and efficient exercise routines.

[0063] The Inertial Measurement Unit (IMU) is a multi-axis sensor that includes a 3-axis accelerometer, gyroscope, and sometimes a magnetometer. The Inertial Measurement Unit (IMU) mentioned herein works in similar manner as discussed above. The IMU measures linear acceleration, angular velocity, and orientation of the user’s movements. The IMU collects motion data in real time, which is used to monitor running form, cadence, balance, and limb stability. The sensor provides crucial input for gait analysis and biomechanical feedback. The microcontroller analyzes this data to detect irregularities, adjust treadmill 103a parameters, or provide feedback for improving posture and performance. Continuous IMU input ensures the runner maintains proper technique throughout training, minimizing injury risk and optimizing biomechanics.

[0064] A wearable microfluidic patch attached to the inner periphery of the wearable band 106 for non-invasive sweat collection, coupled with an optical sensor configured to analyze sweat composition to monitor hydration status and detect early signs of dehydration or muscular fatigue.

[0065] The wearable microfluidic patch consists of a network of microchannel fabricated from biocompatible polymer materials such as PDMS (Polydimethylsiloxane). These channels are designed to passively collect sweat from the skin surface using capillary action, without causing any discomfort or requiring invasive procedures. The patch is affixed to the inner side of the wearable band 106, maintaining close skin contact. The microfluidic layout allows controlled flow of sweat to designated sensing chambers or reservoirs, ensuring sample integrity. The patch may include one-way valves or reservoirs to store sweat and prevent contamination or evaporation, that operates without power, enabling continuous, passive sweat sampling.

[0066] The optical sensor integrated with the microfluidic patch employs spectroscopic methods, absorbance or fluorescence spectroscopy, to analyze sweat composition. Light from an LED or laser source is directed through the collected sweat sample within the microchannel. Changes in light absorption or emission, based on biomarkers like sodium, potassium, lactate, or glucose levels, are detected by a photodetector. These optical signals are then converted into electrical data reflecting the user’s hydration or fatigue status. The sensor is calibrated to detect concentration changes accurately and sends this data to the microcontroller, enabling real-time monitoring and early alerts for dehydration or muscular fatigue.

[0067] For example, during a virtual marathon simulation of the Boston marathon route, the wearable band 106 continuously monitors the runner's heart rate, oxygen level, skin temperature, and movement. If the user begins to overheat or shows signs of fatigue such as increased temperature or reduced oxygen saturation the microcontroller automatically reduces treadmill 103a intensity and lowers ambient temperature, ensuring safety while maintaining an effective training experience tailored to the runner’s physiological condition.

[0068] A holographic projection unit 108 positioned inside the housing 101 is configured to generate life-sized holograms of elite marathon runners using either preloaded or real-time data. These holograms replicate realistic running motions and speeds, accurately reflecting authentic athletic styles. The holographic display is synchronized with motion sensors and speed trackers embedded in the treadmill 103a to maintain consistent pacing with the user, effectively simulating a competitive race environment during training sessions.

[0069] The holographic projection unit 108 employs a laser-based or digital light processing (DLP) system to project high-resolution, three-dimensional visuals into open space, forming life-sized holograms. The unit uses spatial light modulation to manipulate light at precise angles, rendering realistic holograms viewable from multiple perspectives. Preloaded or live data—such as runner movement, posture, and speed is processed by the microcontroller and converted into dynamic 3D projections. The projection surface or medium may include mist, glass, or transparent display films to enhance image clarity.

[0070] Motion sensors, are embedded within the treadmill 103a to detect speed, acceleration, step cadence, and stride pattern of the user. These sensors continuously capture biomechanical movement and transmit real-time data to a control unit. The captured signals are used to assess running dynamics and provide input to other modules, like the holographic unit, for synchronized visual feedback. The sensors work by measuring inertial forces and angular velocities, offering precise tracking of foot placement, user balance, and treadmill 103a belt interaction.

[0071] Speed trackers use rotary encoders or Hall-effect sensors connected to the treadmill’s drive system to monitor belt rotation and calculate user speed. These trackers measure angular displacement or magnetic field changes to generate accurate data on belt speed, which directly correlates with user pace. This data is sent to the microcontroller and projection unit 108, enabling dynamic adjustment of hologram speed to match the user's pace. The trackers also support feedback control to adjust treadmill 103a resistance or incline based on training requirements.

[0072] A high-pressure oxygen cylinder 111 equipped with a regulated flow valve 112 is incorporated into the housing 101, designed to deliver controlled levels of ambient oxygen enrichment to the user throughout training sessions.

[0073] The high-pressure oxygen cylinder 111 is a sealed container designed to store oxygen gas at pressures ranging between 1500 to 3000 psi. Constructed from durable, high-strength materials like aluminum or steel, the cylinder 111 maintains gas integrity and prevents leaks. During operation, the cylinder 111 serves as the primary reservoir of oxygen used for enrichment. The stored gas remains pressurized until released through the regulated valve 112. The pressure is maintained constantly to ensure uninterrupted supply. A built-in pressure gauge indicates the current level of oxygen. The cylinder 111 can be refilled as needed and is securely mounted within the housing 101 for safety.

[0074] The regulated flow valve 112 is connected to the high-pressure oxygen cylinder 111 to manage the flow rate of oxygen released into the training environment. The valve 112 converts the high-pressure oxygen to a lower, usable pressure suitable for safe inhalation. The valve 112 includes a diaphragm and spring-based regulator to maintain a steady output pressure, regardless of variations in cylinder 111 pressure. The valve 112 can be adjusted manually or automatically by the system's microcontroller to deliver variable oxygen concentrations based on user requirements. This regulation helps ensure optimized oxygen delivery, improving performance while preventing hypoxia or excess exposure.

[0075] The microcontroller maintains a database of user biometric information, performance history, environmental preferences, and training configurations. The microcontroller continuously analyzes this data to identify patterns and trends, enabling to adapt and personalize future training sessions. Over time, the system becomes more efficient and responsive to the user’s needs, enhancing workout effectiveness, comfort, and safety by delivering a dynamic, data-driven indoor 102 marathon training experience to individual progress and conditions.

[0076] The present invention works best in the following manner, where the housing 101 as disclosed in the invention, enables controlled and immersive environment for runners. The user gains access through the hinged door 102 upon successful authentication via the imaging unit 114 integrated with the infrared proximity sensor. Once inside, the user is positioned on the treadmill arrangement 103, which is mounted on the multi-axis motion unit 103b. The treadmill 103a dynamically simulates real-world terrain variations through motor-controlled adjustments of speed, incline, decline, and lateral shifts, guided by terrain simulation data. The array of sensors, including the load sensor, gyroscope, and accelerometer, continuously monitor the user's form, balance, and gait cycle. This feedback is relayed to the microcontroller, which in turn adjusts treadmill 103a movements in real time to improve biomechanics and training accuracy. The wearable band 106 equipped with the sensing module 107 monitors real-time physiological parameters such as heart rate, oxygen saturation, body temperature, and motion data through IMU. These inputs enable the microcontroller to modify environmental factors and workout intensity for user safety and performance enhancement. The weather adjustment module 105 within the housing 101 simulates external environmental conditions through coordinated control of the variable-speed fan 105a, LED 105b lighting via ball-and-socket joint 105c, Peltier unit, and motorized iris-lidded air holes 109. External weather data is fetched via the internet-connected forecasting module using GPS-synchronized virtual location data. The holographic projection unit 108 displays life-sized elite runners as pacing guides, enhancing motivation. Sweat analysis is performed via the wearable microfluidic patch and optical sensor, while ambient oxygen is enriched through the regulated high-pressure oxygen cylinder 111. The microcontroller continuously stores and learns from user data to deliver adaptive, personalized training experiences.
