What a 2:05 half marathon predicts

Estimate

Estimated times at other distances (Riegel formula)
Distance	Estimated time
5K	27:10
10K	56:39
10 miles	1:33:49
Marathon	4:20:37

These are estimates from the Riegel formula, T2 = T1 × (D2 ÷ D1)^1.06. They assume you’ve trained for the other distance, so treat them as a guide, not a promise.

Around two hours, steady beats fast

Two hours is the classic half marathon target. In this band being steady matters more than being quick: an even pace to 15 km, then whatever you have left.

You’ll be out for around two hours, so fuel for it: something in the first hour and again in the second, practised in training.

Three or four runs a week with one longer run build to this. If the long run creeps towards two hours, keep it gentle.
