What a 1:15 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.
From 1:10 to 1:25, the middle kilometres decide it
The opening kilometres feel controlled. The race is decided between 10 and 16 km, when holding pace starts to hurt and the finish is still a long way off.
Tempo runs and threshold intervals do most of the work, with a long run each week.
A gel around halfway is worth testing in training. Some runners race this fast without one; find out which suits you before race day.
Pace questions runners ask
- What pace do I need for a 1:15 half marathon?
- A 1:15 half marathon is 3:33/km (5:43/mi), 16.9 km/h, held for the whole race.
- What treadmill speed is 1:15 half marathon pace?
- Set the treadmill to 16.9 km/h or 10.5 mph to run 3:33/km (5:43/mi).
- Where should I be at halfway in a 1:15 half marathon?
- With even pacing you pass halfway in 37:30; with a negative split, a little later.
- What does a 1:15 half marathon predict for other distances?
- The Riegel formula estimates 16:18 for the 5K, 34:00 for the 10K, 56:17 for the 10-mile race, 2:36:22 for the marathon, assuming you’ve trained for each distance.
