How Triathlon Time Is Calculated

Total triathlon time is the sum of all three legs plus transitions.

Formula

Total = Swim Time + T1 + Bike Time + T2 + Run Time

Standard Distances

  • Sprint: 750m swim, 20km bike, 5km run
  • Olympic: 1500m swim, 40km bike, 10km run
  • Half Ironman (70.3): 1900m swim, 90km bike, 21.1km run
  • Ironman: 3800m swim, 180km bike, 42.2km run
  • Example Calculation

    Olympic distance triathlon: 1500m swim, 24.8mi bike, 6.2mi run.

    1. 01Swim = 120 * 1500 / 100 / 60 = 30.0 min
    2. 02T1 = 3 min
    3. 03Bike = 24.8 / 18 * 60 = 82.7 min
    4. 04T2 = 2 min
    5. 05Run = 9 * 6.2 = 55.8 min
    6. 06Total = 30.0 + 3 + 82.7 + 2 + 55.8 = 173.5 min = 2 hr 54 min
