What a 3:35 marathon takes

Riegel’s formula, the one Run 42 uses for every pace in your plan, puts these times on the same level:

  • 5K · 22:25
  • 10K · 46:44
  • Half marathon · 1:43:07

A recent 10K faster than 46:44 says the speed is there; the long runs of a plan build the rest. Slower than that, the race time predictor gives a goal to start from.

In VMA terms, a 3:35 marathon needs 14.4 to 15.7 km/h: the lower figure for a runner with strong endurance, the higher one for most amateurs. See VMA for the marathon.
