How to use it

Enter a distance and target time to get your pace, or work the other way round. For example, 10K in 45:00 → 4:30/km. Custom accepts any distance in km, and the result updates as you type.

What you need to know

The calculation assumes an even pace throughout. It does not predict performance or account for course profile, weather, fuelling or race fatigue. For a prediction, use the Race Predictor; for elevation changes, use GAP. To divide your time into splits, use the Split Calculator.
