About this calculator

Triathlon Distances

Triathlon races vary significantly in distance, from the fast-paced Sprint to the grueling Ironman. Accurate pacing and efficient transitions are key to achieving your target time.

💡

Pro Tips

Practice your transitions—T1 (swim-to-bike) and T2 (bike-to-run) are 'free' speed.
Pacing on the bike is critical; go too hard and you'll suffer on the run.
Stay hydrated and fueled, especially for Half and Full Ironman distances.

Fun Facts

"The first modern triathlon was held in San Diego, California, in 1974."
"An Ironman consists of a 2.4-mile swim, 112-mile bike ride, and a 26.2-mile marathon."
"Drafting is prohibited in most age-group triathlons, meaning you must keep space between bikes."
