Triathlon time calculator
A triathlon is three races and two transitions, and the transitions are where amateurs lose the most time for the least effort.

- Swim distance = 1900
- Swim pace per 100 m = 2
- Bike distance = 90
- Bike speed = 30
- Run distance = 21.0975
- Run pace per km = 5.5
- Transition 1 = 3
- Transition 2 = 2
- Swim split = 1900 / 100 * 2 * 60 = 2280
- Bike split = 30 > 0 ? 90 / 30 * 3600 : 0 = 10 800
- Run split = 21.0975 * 5.5 * 60 = 6962.18
- Transitions = (3 + 2) * 60 = 300
- Total time = 2280 + 10 800 + 6962.18 + 300 = 20 342.2
- Bike as a share of the day = 20 342.2 > 0 ? 10 800/20 342.2*100 : 0 = 53.0917
- Transitions as a share = 20 342.2 > 0 ? 300/20 342.2*100 : 0 = 1.474 77
Values are shown to six significant figures here; the arithmetic itself runs on exact fractions and is only rounded where a number is printed.

The formula
- total = swim + T1 + bike + T2 + run
The default distances are a half-distance triathlon: 1.9 km swim, 90 km bike, 21.1 km run.
