What a 2:35 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 · 33:42
  • 10K · 1:10:15
  • Marathon · 5:23:10

A recent 10K faster than 1:10:15 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.
