Marathon Race Split Calculator/Predictor

This calculator can be used to compute even effort splits for your time goal based on a flat course. The effects of terrain and/or wind conditions are NOT taken into consideration.

Using your recent race performances, the calculator will PREDICT a second set of splits for you based on your current ability as indicated by the performance you have listed.
