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 | Distancekm | Goal time |
| Transition 1 | Time | |
| Bike | Distancekm | Goal time |
| Transition 2 | Time | |
| Run 2 | Distancekm | Goal time |
Enter each transition time as minutes:seconds (ex - 2:30), and each sport time as hours:minutes:seconds (1:15:00).
Edit pacing details below and your finish time & race summary will update accordingly.

Endurance Grid is here to help you understand the sport, decide if it’s the right fit, and learn how to prepare. For course distances, logistics, and race-day specifics, always defer to the race organizer’s event page.
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.
