What a 1:55 half marathon predicts
Estimate| Distance | Estimated time |

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.
Between 1:40 and 1:55, a few seconds per km change the goal
Two round-number goals sit in this band, 1:45 and 1:50. The ladder above shows how few seconds per km separate them, which makes it easier to pick the one you can hold.
Easy long runs and one session a week at goal pace or a little quicker get most runners here. Practise goal pace near the end of a long run, when your legs are tired.
Plan a gel or a few mouthfuls of sports drink around halfway, and take water when it’s offered.
