learn.whatIsHeading

A marathon calculator converts between finish time, pace per km/mile, and average speed for the 42.195km (26.2 mile) marathon distance. Accurate pace prediction allows runners to plan even splits and avoid "hitting the wall" by going out too fast.

公式

Pace per km = Finish time (minutes) / 42.195

分步指南

1Pace per km = Finish time (minutes) / 42.195
2Pace per mile = Finish time (minutes) / 26.2188
3The wall typically hits at 30–35km when glycogen stores are depleted
4Negative splitting (running second half slightly faster) is the optimal race strategy
