Set a goal time for each leg to see the pace you need to hold — and your total duathlon finish time.
Pick a race distance and set a goal time for the first run, the bike, and the second run. The calculator shows the pace you need on each leg — run pace per mile and bike speed — and adds it all up, with your transitions, into a total finish time. The second run is usually slower off the bike, so give it its own honest target.
| Leg | Distance | Goal time |
|---|---|---|
| Run 1 | km | |
| Transition 1 | — | |
| Bike | km | |
| Transition 2 | — | |
| Run 2 | km |
Enter each transition time as minutes:seconds (ex - 2:30), and each sport time as hours:minutes:seconds (1:15:00).
Tap a pace to set your own for that leg — the finish time updates to match.
| Leg | Split | Pace | Cumulative |
|---|---|---|---|
| Run 1 | 30:00 | / km | 0:30:00 |
| Transition 1 | — | 0:32:00 | |
| Bike | 40:00 | km/h | 1:12:00 |
| Transition 2 | — | 1:14:00 | |
| Run 2 | 16:00 | / km | 1:30:00 |

With duathlon, two disciplines push you in completely different ways. Duathlon rewards athletes who refuse to specialize — and if you've ever wanted to know what your legs can do after an all-out bike leg, this is your sport.
Run, bike, run. The multi-sport format without the swim. Two disciplines, one race — a great bridge between running and triathlon.
