Predict race times

predict_race_time

Predict times across 5K / 10K / Half / Marathon from a known race result, using a distance-varying Riegel exponent (1.06 up to 10K, 1.07 to the half, 1.08 to the marathon) and age-graded performance scores against world records. Predictions are point estimates with no confidence interval — treat a marathon predicted from a short race as an optimistic ceiling. Source: ham.run race predictor. Pass useMyData:true to overlay age + sex from the connected athlete profile.
