Track Lap
Track Lap is an interactive sandbox app that lets you explore different sprint race scenarios. You can replay real races from the last few years or alter runner characteristics to see how changes in Fmax, acceleration, and propulsive force deterioration affect pacing and the outcome.
Built to encourage experimentation, the app allows you to test what-if scenarios and see the results through smooth, animated race visualisations. The app is built in R Shiny with JavaScript-based animations.
The model used to develop the race profiles is based on an open access article I published in 2025.
