What a 2:45 marathon predicts
Estimate| Distance | Estimated time |
|---|---|
| 5K | 17:12 |
| 10K | 35:52 |
| 10 miles | 59:24 |
| Half marathon | 1:19:08 |
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.
Breaking three hours takes a patient first half
Sub-3 is a classic club-running goal, and the start line is full of people trying for it. Don’t follow the crowd out at the gun. Run your own splits from the first kilometre.
Training usually centres on a weekly long run, with sections at goal pace in the later weeks, plus one quality session such as a tempo or threshold run. Keep easy days easy, so the hard days count.
You’ll race for close to three hours, so fuel from early on, not when you start to fade. Use the gels or drink you’ve tested in long runs. Race day is the wrong day for a new brand.
