What a 4:45 marathon takes

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

  • 5K · 29:43
  • 10K · 1:01:57
  • Half marathon · 2:16:42

A recent 10K faster than 1:01:57 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 4:45 marathon needs 11.1 to 11.8 km/h: the lower figure for a runner with strong endurance, the higher one for most amateurs. See VMA for the marathon.
