StrideIQ is a running form analysis tool that empowers runners to assess their technique by uploading a short side-view video. The application is designed for anyone who runs—from beginners curious about their stride to experienced athletes monitoring efficiency—offering a quick, convenient verification without the need for a professional gait analysis lab. By analyzing just a few seconds of footage, StrideIQ highlights common form issues and provides data-driven recommendations, making it an accessible entry point into running biomechanics. Its core value lies in democratizing running form analysis, turning a smartphone video into actionable feedback in seconds.
Many runners suffer from injuries caused by inefficient form, yet access to professional gait analysis remains limited and costly. Runners often have no easy way to check if their overstride, heel strike, or pelvic drop is contributing to knee pain or shin splints. Without objective feedback, subtle problems persist, potentially leading to chronic issues. StrideIQ addresses this gap by offering a free, immediate self-assessment that can be done anywhere. It provides the first line of defense—a quick sanity check that helps runners decide if they need deeper coaching or medical attention, reducing the guesswork and anxiety around form-related injuries.
The analysis process begins with capturing a side-view video that meets specific criteria for reliable results. StrideIQ requires a clip of at least 3 seconds of real-time running, containing 4–6 strides, filmed with the camera fixed at roughly hip height and the runner moving consistently left‑to‑right or right‑to‑left. The tool supports 1080p footage at 30 fps, which is typical for modern smartphones, and also accepts 240 fps slow‑motion video from devices like the iPhone’s Slo‑mo mode. Good lighting and a subject that fills 60–90% of the frame height are recommended to ensure the algorithm can accurately track body position. These guidelines maximize the signal for the computer vision model, allowing it to reliably detect contact events and segment the stride.
Once the video is uploaded, users can choose between two analysis modes: Lite and Full. Lite mode is the default, optimized for faster processing and adequate for a quick initial check. Full mode delivers higher accuracy by using a more computationally intensive algorithm, which is better suited for detailed biomechanical scrutiny. This tiered approach gives runners the flexibility to balance speed and depth; a coach might use Lite to screen multiple athletes rapidly, then switch to Full for an in‑depth evaluation when needed. Both modes output the same types of results—form flags, metrics, and recommendations—but Full mode provides more precise skeleton tracking and finer detection of subtle movement patterns.

After processing, StrideIQ presents three categories of results. Form Flags highlight potential issues in your running form, alerting you to areas that may need attention. Key Metrics, derived from detected contact frames, display median estimates along with an interpretation to help users understand what the numbers mean for their performance and injury risk. The Recommendations section offers practical, running‑economy‑oriented advice, suggesting adjustments that could make the runner’s stride more efficient. Users can also download a JSON file containing the full analysis for further review or to track changes over time, and a debug log is available for those who want to understand the tool’s processing steps.
The underlying workflow of StrideIQ is a straightforward upload‑and‑analyze pipeline. When a video is uploaded, the system first validates that it meets the framing and formatting requirements. Then it uses a pose‑estimation model to place a skeleton overlay on each frame, identifying joint positions throughout the running cycle. By analyzing the displacement of key points (hips, ankles, knees) and detecting ground‑contact events, the algorithm computes metrics and identifies deviations from an ideal baseline. This all happens in the browser, so no video leaves the user’s device, preserving privacy. The generated skeleton overlay is displayed alongside the original footage, providing a visual reference for the runner. With a single click, the user can start the analysis and receive results within moments, making the entire process seamless and immediately informative.
Runners find StrideIQ valuable in several real‑world scenarios. A marathon trainee might upload a video after a long run to check if fatigue is causing a heel strike that wasn’t present earlier. A runner returning from an ankle sprain could use the tool to visually confirm that their gait remains symmetrical and that compensation patterns have not developed. Physical therapists can assign a quick home video as a supplement to in‑person assessments, allowing them to monitor progress between appointments. Running coaches can evaluate multiple athletes’ form before group sessions, using the downloadable JSON data to create individual reports and track improvements across a season. Even casual joggers use StrideIQ out of curiosity, gaining a better understanding of how small adjustments like posture or arm swing affect their efficiency.
StrideIQ is built for runners of every level, but it also appeals to running coaches, physiotherapists, and sports scientists who need a lightweight, immediate analysis tool. The application runs entirely in a web browser, requiring no software installation and working on any device that can decode video. Its compatibility with standard phone video formats and slow‑motion captures makes it accessible to the vast majority of smartphone users. While the tool does not replace professional motion capture, it serves as a powerful first‑pass screening and educational resource. In summary, StrideIQ brings the essentials of running form analysis into the hands of anyone with a phone, making biomechanical insight a routine part of running smart and staying injury‑free.
StrideIQ targets runners of all abilities—from beginners who want to understand their natural stride to competitive runners seeking marginal efficiency gains. It is equally valuable for running coaches who need a quick, data‑backed way to evaluate multiple athletes, and for physical therapists and sports medicine professionals who can use it as a home‑exercise monitoring tool. Sports scientists and researchers may also find it useful for preliminary screenings or large‑scale studies where a full lab setup is not feasible. Because the tool runs entirely in a browser with no login required, it removes barriers for anyone curious about their running biomechanics. The key users are individuals who will benefit from regular, objective form checks without investing in specialized hardware.
