1:40 Half Marathon Pace
To finish a 1:40 half marathon in 1:40:00, you need to average 4:44 per kilometer — that's 7:37 per mile, or 12.7 km/h (7.9 mph) held for the full 21.0975 km.
This is a solid, above-average half marathon time for a trained recreational runner.

Is 1:40:00 realistic for you?
Race times scale predictably across distances (we use the Riegel formula). If your recent results are close to these equivalents, a 1:40 half marathon is within reach:
| Distance | Equivalent time | Pace |
|---|---|---|
| Marathon | 3:28:30 | 4:56 /km |
| 10K | 45:19 | 4:31 /km |
| 5K | 21:44 | 4:20 /km |
These assume similar training for each distance — check your own numbers with the Pace Calculator.
