How We Calculate This
Interval Calculation
Run and walk interval durations are based on your current running ability. Average speed = (run fraction x run speed + walk fraction x walk speed) / terrain factor.
Predicted Finish Time
Finish time = distance / average speed, accounting for the proportion of time spent running versus walking and terrain difficulty.
