4:05 per mile pace
4:05 min/mile is genuinely elite territory — the pointy end of national-class racing. Here’s what it does over every distance, in plain maths — then the harder question of when to run it.

Race times at 4:05 per mile
Every finish below assumes you hold 4:05 /mi evenly the whole way — a useful yardstick, not a prediction. Real races fade; the pace calculator does the Riegel-adjusted version from a race you’ve actually run.
| Distance | Finish time | Pace /km |
|---|---|---|
| Mile | 4:05 | 2:32 |
| 5K | 12:41 | 2:32 |
| 10K | 25:22 | 2:32 |
| 15K | 38:04 | 2:32 |
| Half marathon | 53:32 | 2:32 |
| Marathon | 1:47:04 | 2:32 |
Is 4:05 per mile a good pace?
Honestly, the number matters less than the day it lands on. 4:05 /mi is genuinely elite territory — the pointy end of national-class racing. If it’s your goal-race pace, most of your training should happen slower than this — the fastest way to a faster race is a pile of easy kilometres and a handful of hard ones, run on the right days. If it already feels easy, it’s a fine cruising pace to build your base on.
A pace chart can tell you the maths. It can’t tell you whether today is a day to hit it — that depends on your sleep, your legs, and the runs already behind you. That gap is exactly what Liftrun was built to close.
