Wind-Affected Performance Calculator
Convert a recorded performance to its estimated still-air equivalent, then predict what the same performance could look like with a different headwind or tailwind. For sprints, hurdles, long jump, and triple jump.
What would you run—or jump—with different wind?
Enter a known performance and the wind recorded with it (use 0.0 if it was in still air). Then choose a hypothetical wind. See your estimated performance at both 0.0 m/s and the wind you selected.
Based on published population-average coefficients (2018). These are hypothetical estimates, not official marks or guaranteed performances.
How this wind calculator works
First, the model estimates how the recorded wind helped or hindered the performance and converts it to 0.0 m/s. Next, it applies the modeled effect of your chosen hypothetical wind to estimate what you might run or jump under those conditions.
Our baseline uses event-specific coefficients published by Moinat, Fabius & Emanuel (2018), who analyzed more than 150,000 athletics results and fitted a mixed-effects wind-performance model. For four event groups, the estimated advantage is ΔP = a × wind + b × wind²; long jump uses the published linear fit.
Sprints and hurdles: projected time = entered time + A(recorded wind) − A(target wind).
Long jump and triple jump: projected distance = entered distance − A(recorded wind) + A(target wind).
Still air: set target wind to 0.0 m/s.
For example, a 100m time of 11.20 s recorded at 0.0 m/s projects to roughly 11.07 s at +2.0 m/s in this average model. A following wind typically reduces sprint time or increases jump distance; a headwind generally has the opposite effect. Real responses vary, and the paper found performance-level differences in the 100m. We therefore use the study's population-average coefficients, not individualized predictions.

Wind adjustment by event
These published average coefficients differ by event. At a +2.0 m/s tailwind, the model estimates the following advantages before returning results to a 0.0 m/s reference.
| Event | Approximate +2.0 m/s advantage | Result being adjusted |
|---|---|---|
| 100m | 0.125 s faster | Time |
| 200m | 0.140 s faster | Time |
| 100m / 110m hurdles | 0.146 s faster | Time |
| Long jump | 0.058 m farther | Distance |
| Triple jump | 0.102 m farther | Distance |
All figures are approximations from a population-level model. The 100m numbers shown here use the paper's average model, not a performance-dependent correction.
Frequently asked questions
What is considered wind-aided in track and field?
For the usual individual events where horizontal wind is measured—100m, 200m, 100m/110m hurdles, long jump, and triple jump—a recorded tailwind greater than +2.0 m/s exceeds the standard record wind limit. Event-specific and combined-event rules may differ. A wind reading below the limit alone does not establish full record or qualification eligibility.
What does +2.0 or −2.0 wind mean?
+2.0 m/s is a tailwind blowing in the direction of the run or jump. −2.0 m/s is a headwind against the athlete. A positive reading generally assists performance; a negative reading generally hinders it.
Can a wind-aided result still win a race?
Yes. Exceeding the wind limit does not nullify an otherwise valid competition result. Wind assistance typically affects record ratification and some statistical or qualifying uses, subject to the applicable rules.
What would I run with a +2.0 m/s tailwind?
Enter your known time and its wind reading, then set the what-if wind to +2.0 m/s. For example, an 11.20 s 100m run at 0.0 m/s projects to approximately 11.07 s at +2.0 m/s under this population-average model. Actual outcomes can differ.
Can I compare a headwind result with a tailwind scenario?
Yes. Enter the wind from your original race as a negative value, then enter a positive target wind. The calculator first estimates still air and then applies the new wind. These projections are not official times or qualifying marks.
Are projected sprint times official personal bests?
No. Predicted times and distances are modeling estimates. Your official mark remains the time or distance recorded in the competition.
Why can't I use the same formula for discus, shot put, or pole vault?
Wind can affect many events physically, but they do not use the same horizontal-wind measurement rules or empirical adjustment model. This tool covers only the events with event-specific published coefficients.
