What it calculates
The “Running Riegel Formula” calculator computes Predicted time (Riegel) in min from 4 parameters: known distance (km), time over known distance (min), target distance (km), riegel exponent.
A study aid and exam-prep helper.
Example calculation
With parameters Known distance = 10 km, Time over known distance = 50 min, Target distance = 21.1 km, Riegel exponent = 1.06 the result is 110.3 min (Assumes equal training for both distances; less accurate beyond the marathon).
