Triathlon Pace Calculator

Set a goal time for each leg to see the pace you need to hold — and your total triathlon finish time.

Pick a race distance and set a goal time for the swim, bike, and run. The calculator shows the pace you need to hold on each leg — swim pace per 100m, bike speed, run pace per mile — and adds it all up, with your transitions, into a total finish time. Adjust any leg to see the total move.

Open water, open roads, and competition with yourself. Cross the finish line knowing what it took to get there.

Triathlon

Swim, bike, run — back to back. The sprint distance makes it far more accessible than most people think. Three sports in one race means three movements to train and race day never gets monotonous.

Frequently Asked Questions

How do I calculate my triathlon splits?
Set a goal time for each leg — the swim, the bike, and the run — and the calculator shows the pace that time requires (swim pace per 100m, bike speed, run pace per mile), then adds your legs and transitions into a total finish time. Adjust any leg and the total updates.
Does the calculator include transitions?
Yes. T1 (swim to bike) and T2 (bike to run) are separate time fields that count toward your finish time. They default to two minutes each — edit them to match how quick your transitions really are.
What race distances does this triathlon pace calculator handle?
This triathlon pace calculator covers the standard triathlon distances, like Sprint, Olympic, 70.3, and Ironman. You can adjust your own goal time for each leg. The calculator can be used to track pacing for any triathlon distance to help you track your goal time, pace by split, and split time.
