Triathlon Time Math: Adding Up Swim, Bike, Run, and Transitions
A triathlon finish is five numbers, not three. Adding the transitions in stops the classic surprise of a finish time that looks faster than it really was.
What is the Triathlon Time Calculator?
Enter each leg and both transitions in minutes, and the tool totals them into a finish time in hours and minutes with each leg's share. It is simple addition, so it works for any distance from sprint to full, as long as every leg is entered in minutes.
How to use it
- Enter each leg in minutes.
- Enter both transition times in minutes.
- Click Calculate Total Time.
Worked example
Swim 30, T1 3, bike 150, T2 2, and run 90 minutes total 275 minutes, or 4h 35m, with the bike taking about 54.55% of the race.
How long is a 30-3-150-2-90 triathlon?
275 minutes, or 4 hours 35 minutes, once both transitions are included in the total.
Frequently asked questions
Do I count transitions?
Yes. The race clock runs through transitions, so leaving them out understates your finish time.
Can I use it for any distance?
Yes. It only adds minutes, so sprint, Olympic, half, and full distances all work.
