What a 1:50 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.
Pace questions runners ask
- What pace do I need for a 1:50 half marathon?
- A 1:50 half marathon is 5:13/km (8:23/mi), 11.5 km/h, held for the whole race.
- What treadmill speed is 1:50 half marathon pace?
- Set the treadmill to 11.5 km/h or 7.2 mph to run 5:13/km (8:23/mi).
- Where should I be at halfway in a 1:50 half marathon?
- With even pacing you pass halfway in 55:00; with a negative split, a little later.
- What does a 1:50 half marathon predict for other distances?
- The Riegel formula estimates 23:55 for the 5K, 49:51 for the 10K, 1:22:33 for the 10-mile race, 3:49:21 for the marathon, assuming you’ve trained for each distance.
