What a 2:40 marathon takes
Riegel’s formula, the one Run 42 uses for every pace in your plan, puts these times on the same level:
- 5K · 16:41
- 10K · 34:47
- Half marathon · 1:16:44
A recent 10K faster than 34:47 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 2:40 marathon needs 19.1 to 21.1 km/h: the lower figure for a runner with strong endurance, the higher one for most amateurs. See VMA for the marathon.
