Frequently Asked Questions
How do I calculate my triathlon finish time?
Add up your swim, bike and run split times plus both transitions. Enter your swim pace per 100m, bike speed in km/h and run pace per km above, and the calculator converts them into a total projected finish time for sprint, Olympic, 70.3 or full Ironman distance.
How long does T1 and T2 take in a triathlon?
Transition time depends on the venue layout, equipment, athlete experience, weather, and event procedures. Use your own practice or prior race data when available, and check the athlete guide for long transition routes or special instructions.
What bike speed should I enter?
Use a sustainable estimate from comparable rides rather than a generic benchmark. Wind, elevation, road surface, turns, traffic control, equipment, and pacing can all change race-day speed.
Should I pace a triathlon evenly or negative split?
Use a conservative, sustainable plan based on recent training and the course. The calculator converts the numbers you enter; it cannot determine safe intensity or predict how fatigue, weather, nutrition, or terrain will affect you.
