What a 3:25 marathon takes

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

  • 5K · 21:22
  • 10K · 44:34
  • Half marathon · 1:38:19

A recent 10K faster than 44:34 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 3:25 marathon needs 15.1 to 16.5 km/h: the lower figure for a runner with strong endurance, the higher one for most amateurs. See VMA for the marathon.

Most of the week is easy running; threshold and VMA come in one or two sessions a week. See training pace zones for what each one does.
