What a 1:40 10-mile race predicts

Estimate

Estimated times at other distances (Riegel formula)
Distance	Estimated time
5K	28:58
10K	1:00:23
Half marathon	2:13:14
Marathon	4:37:48

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.

Over 1:30, keep it even and keep eating

Over an hour and a half, eat and drink on a schedule. Run/walk intervals from the start keep the pace even.

Check the cut-off time, and wear shoes you’ve already run long in.
