# Track Wind Calculator: Sprints, Hurdles, Jumps

> Wind calculator for the 100m, 200m, hurdles, long jump and triple jump: still-air, +1 and +2 m/s equivalents, and whether your reading was legal.

**A +2.0 m/s tailwind is worth about 0.09s to 0.14s in the 100m depending on your pace (0.111s at 11.50), a flat 0.14s in the 200m, and about 6cm in the long jump, from the published Moinat 2018 model.**

Enter your mark and the wind reading for the 100m, 200m, hurdles, long jump or triple jump. See what it is worth in still air and at +1.0 and +2.0 m/s, and whether the reading was legal. Built on the published Moinat 2018 model.

## Worked example

A 100m of **10.80** with a +2.0 m/s wind is worth **10.90** in still air, 10.84 at +1.0 and 10.80 at +2.0. Enter your own mark and wind above for yours.

## When you need this

Every sprint, hurdles and horizontal-jump result carries a wind reading, and it changes what the mark means. A 10.80 into a headwind and a 10.80 with the maximum legal tailwind are not the same run, and the triple jump is roughly twice as wind-sensitive as the long jump. A coach comparing two athletes on paper adjusts for wind before comparing anything else; this shows you what your mark was actually worth.

## How the adjustment works

Wind changes a sprint or a horizontal jump by a measurable amount, and the size of it has
been fitted to real results rather than argued from theory. The model here is Moinat and
colleagues (2018), published in the European Journal of Sport Science and fitted to 150,169
elite and sub-elite performances. A tailwind at the legal limit of +2.0 m/s
is worth roughly 0.125s over 100m, 0.140s over 200m, 0.146s in the hurdles, 5.8cm in the long
jump and 10.2cm in the triple jump.

The 100m is the one event where the size of the effect depends on how fast you already are:
a slower athlete spends longer in the wind, so they gain more from it. This calculator accounts
for that, which is why two athletes with the same wind reading get different corrections.

**No governing body adjusts a result for wind.** A mark is what the clock or the tape
said. What the wind reading decides is whether it is *legal*: at or under
+2.0 m/s it can be a record, a qualifying performance and a ranking mark;
over it, the result stands and still wins the competition but carries a w and cannot be used
for any of those things. Use this to understand what a mark was worth, never to claim one.

Fitted on 150,169 elite and sub-elite results. Coefficients are copied from the authors' own published calculator. No federation adjusts a result for wind.

## What a legal tailwind is actually worth

Every row below is the same published model the calculator uses. Notice the 100m column:
the correction grows with the time, from under a tenth at 10.50 to nearly 0.14s at 13.00,
so no single "wind is worth X" number is right for everyone.

### 100m: marks run with a +2.0 m/s tailwind, in still air

| With +2.0 wind | Still air | The wind was worth |
| --- | --- | --- |
| 10.50 | 10.59 | 0.092s slower |
| 11.00 | 11.10 | 0.101s slower |
| 11.50 | 11.61 | 0.111s slower |
| 12.00 | 12.12 | 0.120s slower |
| 12.50 | 12.63 | 0.130s slower |
| 13.00 | 13.14 | 0.139s slower |

### 200m: marks run with a +2.0 m/s tailwind, in still air

| With +2.0 wind | Still air | The wind was worth |
| --- | --- | --- |
| 21.50 | 21.64 | 0.140s slower |
| 22.50 | 22.64 | 0.140s slower |
| 23.50 | 23.64 | 0.140s slower |
| 24.50 | 24.64 | 0.140s slower |

### Long Jump: marks run with a +2.0 m/s tailwind, in still air

| With +2.0 wind | Still air | The wind was worth |
| --- | --- | --- |
| 5.50m | 5.44m | 6cm shorter |
| 6.00m | 5.94m | 6cm shorter |
| 6.50m | 6.44m | 6cm shorter |
| 7.00m | 6.94m | 6cm shorter |

No governing body adjusts results for wind. These are estimates for understanding what a
mark is worth, never numbers to claim.

## Then find out what the mark is worth

Converting is the easy half. The number only means something next to a standard, so this
tool also places your converted mark against published NCAA Division I, II, III and NAIA
recruiting ranges for your event and gender, and tells you which of them are realistic. No
other converter does that, and it is the reason to run yours here.

A converted mark is for comparing, not for claiming. Once you know where it sits, the
useful next step is putting the race itself on a profile so a coach can watch it rather than
take your word for the number.

## Common questions

### What wind is legal in track and field?

A tailwind of +2.0 m/s or less. Above that the mark still stands as a result and still wins the race or the competition, but it cannot be a record, a qualifying performance or a ranking mark, and it is written with a w beside it. The limit was set at the 1936 IAAF Congress and has not moved since. The full rulebook picture is in wind-legal marks explained.

### Which events have a wind reading?

The 100m, 200m, 100m hurdles, 110m hurdles, long jump and triple jump. There is no wind rule for the 400m, the distance races, the throws or the vertical jumps, so this calculator refuses them rather than inventing a number.

### Does a wind-aided mark still count?

For placing in that competition, yes, completely. For records, qualifying standards and most ranking lists, no. This is why an athlete can win a race with a time they cannot then use on an entry form.

### How accurate is this adjustment?

It comes from a peer-reviewed model fitted to 150,169 results, so it is a good estimate of the average effect. It is not what any governing body applies: no federation adjusts a result for wind. Use it to understand what a mark is worth, never to claim a time or a distance you did not actually record.
