A Split-Timer Toolbox for Track Athletes
A Japanese athletics calculator that turns race goals and personal bests into splits, predictions, and sprint-profile diagnostics.
Field notes
The site combines several input-driven calculators rather than offering only a single split table. Its main workflow accepts an event, target time, and relevant personal best, then presents 10-metre section and passage times alongside a claimed gap diagnosis. Separate modules compare paired results such as 100m and 200m, estimate jumping potential from 60m and 100m times, and classify running style from height, time, and step count. Results can be saved as images and shared via X or LINE.
