What a 2:25 half marathon takes
Riegel’s formula, the one Run 42 uses for every pace in your plan, puts these times on the same level:
- 5K · 31:31
- 10K · 1:05:43
- Marathon · 5:02:19
A recent 10K faster than 1:05:43 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.
