What a 3:50 marathon predicts
Estimate| Distance | Estimated time |
|---|---|
| 5K | 23:59 |
| 10K | 50:00 |
| 10 miles | 1:22:48 |
| Half marathon | 1:50:19 |
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.
Sub-4 rewards an even first half
Four hours is a common target for a first or second marathon. The usual way to miss it is going out too fast: the first half feels easy, and the bill arrives late.
Walking a few steps through a water station to drink properly costs seconds and can save minutes later. If you plan to do it, plan it into your pacing.
Run your long runs slower than race pace and use them to rehearse everything else: breakfast, shoes, socks and fuel.
Pace questions runners ask
- What pace do I need for a 3:50 marathon?
- A 3:50 marathon is 5:27/km (8:46/mi), 11.0 km/h, held for the whole race.
- What treadmill speed is 3:50 marathon pace?
- Set the treadmill to 11.0 km/h or 6.8 mph to run 5:27/km (8:46/mi).
- Where should I be at halfway in a 3:50 marathon?
- With even pacing you pass halfway in 1:55:00; with a negative split, a little later.
- What does a 3:50 marathon predict for other distances?
- The Riegel formula estimates 23:59 for the 5K, 50:00 for the 10K, 1:22:48 for the 10-mile race, 1:50:19 for the half marathon, assuming you’ve trained for each distance.
