What a 1:39 half marathon predicts
Estimate| Distance | Estimated time |

| Marathon | 3:26:24 |
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.
1:25 to 1:40 is where even pacing pays
Bank time early and you’ll give it back, with interest, in the last 5 km. Hold the same pace from the start and let the effort rise instead.
One quality session a week, a tempo run or intervals at goal pace, plus a weekly long run builds most of what you need. Run the rest easy.
You’ll race for well over an hour and a quarter. A gel or sports drink in the second half helps; use one you’ve tried in training.
