Race Time Predictor

Estimate a race finish time from a recent performance using the Riegel formula.

How to use Race Time Predictor

A race time predictor estimates your finish time for one distance based on a known result from another distance.

Basic idea

Known race time + known distance + target distance = estimated finish time

Is the predicted time guaranteed?

No. It is an estimate. Training, endurance, terrain, weather, and pacing can change the actual result.
