Olympic Triathlon Pace Calculator

Enter your swim pace, bike speed and run pace to get each split and the total Olympic triathlon time.

How it is calculated

The tool uses the fixed Olympic distances and your three paces. swim = 15 × swim_pace (pace in minutes per 100 m, 1500 m is 15 blocks), bike = 40 ÷ bike_speed × 60 (speed in km/h), run = 10 × run_pace (pace in minutes per km). The total is the sum of the three legs. Paces must be entered as decimal minutes, so 1 min 30 s is 1.5, and all three must be above zero. Each time is rounded to the nearest minute for display. Transitions (T1 and T2) are not included, so add a few minutes for them yourself.

Worked example

Swim pace 1.8 min/100 m, bike 32 km/h, run 5.5 min/km. Swim: 15 × 1.8 = 27 min. Bike: 40 ÷ 32 × 60 = 75 min, which is 1h 15m. Run: 10 × 5.5 = 55 min. Total: 27 + 75 + 55 = 157 min, shown as 2h 37m.

Common mistakes

  • Typing a swim pace like 1:45 or 1.45 for one minute 45 seconds. The field takes decimal minutes, so 1 min 45 s is 1.75; the colon form is not accepted.
  • Entering bike speed as a pace (min/km) or run pace as a speed. Bike is km/h, run is min/km.
  • Using a pool pace for open water. Open-water swims are usually slower because of sighting and currents.
  • Forgetting that transitions are not counted, so the real finish time will be longer than the total shown.

About this calculator

This calculator breaks down the official Olympic-distance triathlon — 1.5 km swim, 40 km bike, 10 km run, the distance raced at the Olympic Games — into segment times based on your target swim pace (per 100 m), bike speed and run pace, then sums them into a projected finish time.

Triathletes and coaches use segment-by-segment pacing like this to build a realistic race plan, since going out too hard on the swim or bike leaves little left for the run — the leg where most amateur athletes lose the most time. It's also a useful tool for setting split targets to hit a specific goal finish time.

    Use the tool to see which leg buys the most time per unit of effort. At a 32 km/h bike leg of 1h 15m, dropping to 31 km/h adds about two and a half minutes, which is more than the same slowdown deserves on the swim or run. Remember the swim pace is minutes per 100 m, and a pool pace often does not carry over to open water. Which leg are you hoping to improve this season?
