What a 2:45 half marathon predicts
Estimate| Distance | Estimated time |
|---|---|

| 10 miles | 2:03:50 |
| Marathon | 5:44:01 |
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.
Over 2:15, run the race your way
Run/walk intervals from the start are a sound strategy at this pace and often beat running until you can’t.
Check the race’s cut-off time and keep a comfortable margin.
Over two and a quarter hours, eat and drink on a schedule and carry what you’ve tested. Shoes and socks you’ve already run long in are worth more than new ones on the day.
