Put a windy run into perspective

The exposed part of a route can make the whole run feel harder. Average pace alone does not tell you how much of that difference came from the wind.

A loop estimate, not a headwind predictor

The Running Browser model treats the run as a loop with mixed wind exposure. It uses the wind speed above the default threshold, adjusts weather-station wind towards runner height and relates the remaining wind to running speed.

It does not know which direction each section of your route faced. A point-to-point race into a headwind, a sheltered trail and an exposed loop can therefore need very different interpretations.

Use weather wind speed consistently

Enter the reported wind speed in kilometres per hour. The model already includes its own runner-height adjustment; reducing the input a second time would change the meaning of the result.

With the default settings, wind at or below 5 km/h adds no modeled cost. Above that threshold the estimate grows with wind relative to running speed.

Try one change at a time

Enter a recent pace in the wind calculator, then vary wind speed while keeping pace fixed. This shows what the model attributes to wind alone. Use the weather calculator when temperature, climbing or terrain also mattered.

The result is useful for comparison, but it does not prescribe how fast you should run into a gust or predict a race finish time. Keep the original pace and your notes.

Bring the estimate into your training history

Connect Strava after creating your account to keep imported activities and available conditions together. Running Browser can calculate pace in ideal conditions for your runs and optionally add the estimate to Strava descriptions.
