How accurate is this wind correction?

This tool uses data-driven regression equations from Moinat et al. (2018), estimating wind effects from large race datasets. It provides a strong practical estimate, but factors such as lane position, temperature, altitude, and track surface still matter, so treat results as theoretical approximations.

Can I use a wind-assisted time as an official record?

No. Times recorded with tailwind exceeding +2.0 m/s are not ratifiable as official records. However, the wind-corrected value from this tool can serve as a useful estimate of your actual ability.

How is wind measured in the 200m?

For the 200m, wind speed is measured on the home straight (the final straight). Wind effects on the curve are complex, so only the straight-line wind reading is used in official results.

Can I correct headwind times too?

Yes. Enter a negative wind speed and the tool will estimate your still-air equivalent performance. For running events this is usually a faster time, and for jumps often a longer mark.

How the Calculation Works

This tool uses quadratic regression equations from Moinat et al. (2018). The model provides event-specific coefficients for the 100m, 200m, 100mH, 110mH, long jump, and triple jump, and captures both tailwind and headwind effects with nonlinear terms. The original study fitted these formulas using 150,169 elite and sub-elite results.

Wind correction itself has been studied for decades, including foundational work such as Dapena & Feltner (1987). The model used here builds on that research tradition with a large empirical dataset, making it suitable for day-to-day performance comparison and post-race analysis.

It is also consistent with competition practice: World Athletics requires wind measurement for these events and applies rules around +2.0 m/s tailwinds for record ratification. This tool is designed to align with that official framework while providing a still-air estimate.

About Wind Correction

Why Wind Correction Matters

Wind has a significant impact on sprint times and horizontal jump distances. In the 100m, a ±2.0 m/s wind can shift performances by roughly 0.08-0.12 seconds, and jumps are also meaningfully affected. To compare performances under different wind conditions, converting to still-air equivalents is useful.

What Is a Wind-Assisted Mark?

Under World Athletics rules, any performance achieved with a tailwind exceeding +2.0 m/s is classified as 'wind-assisted' and cannot be ratified as an official record. However, such times are still useful indicators of ability. This tool lets you estimate the still-air equivalent of wind-assisted marks.

Supported Events

This tool supports 100m, 200m, 100mH, 110mH, long jump, and triple jump. Events of 400m and beyond involve running around curves where wind effects are multi-directional, so wind correction does not apply.
