100m Predictor
This 100m predictor estimates race performance from a block 30m split and a flying 10m split, with optional wind and reaction-time adjustments. Use it to translate practice timing into a realistic 100m projection.
Practice Sprint Inputs
t = e^(2.244 + 0.147·b30 − 0.0429·(10÷fly10)) − wind(w) + RT
(exponential model fit on elite results; wind(w) = −0.0449w + 0.00946wt − 0.0042w²)The model is fit on elite and sub-elite men's 100m results and is strongest from roughly 9.6s to 11.1s. Outside that range treat the prediction as a rough guide, not a target.
How coaches use the 100m predictor
Use this 100m predictor when you have acceleration and max-velocity practice timing and need a quick race projection.
- Estimate 100m readiness from block 30m and fly 10m timing-gate sessions.
- Compare neutral, legal-wind, and ideal-reaction scenarios before race week.
- Give sprinters a concrete performance target from practice data.
100m Predictor FAQ
Use a block 30m split, a flying 10m split, wind, and reaction time. The block and fly inputs matter most.
Use fully automatic, timing-gate, or video-derived splits when possible. Hand times usually need adjustment and can make the prediction too optimistic.
