Triathlon Finish Time Predictor

Enter your paces and race distance to predict your finish time and splits across all triathlon formats.

Enter your expected open-water swim pace per 100m. Most recreational triathletes swim 2:00–2:30/100m in open water.

Recreational: 20–25 km/h. Intermediate: 26–32 km/h. Competitive: 33–40 km/h.

Your expected brick run pace (typically 20–45 sec/km slower than your fresh 5K pace for shorter races, more for longer).

Sprint/Olympic: T1 ~2–4 min, T2 ~1–3 min. 70.3/Ironman: T1/T2 each 3–8 min.
