Splits 0:30:00 swim + 1:10:00 bike + 0:50:00 run → 2:30:00 total (~51.50 km course).
Total time is the arithmetic sum of your three leg durations. Pace metrics divide each leg’s time by that leg’s distance in standard multisport units (meters for swim pace blocks, kilometers for bike and run).
Total time = Swim time + Bike time + Run timeSwim pace /100m = Swim time ÷ (Swim meters ÷ 100)Bike km/h = Bike km ÷ (Bike hours)Run pace /km = Run time ÷ Run kmDial in the swim with the swimming pace calculator.
