What a 2:05 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 · 27:10
- 10K · 56:39
- Marathon · 4:20:37
A recent 10K faster than 56:39 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.
