How to Use the Triathlon Pace Calculator
This triathlon pace calculator distributes your goal finish time across swim, bike, and run disciplines. Select your race distance, enter your goal time, and see required paces for each segment.
Time Distribution by Distance
This calculator uses standard time ratios: swim ~15%, bike ~55%, run ~30% of total time (minus transitions). For an Olympic triathlon in 2:30:00: swim ~22min, bike ~82min, run ~45min, transitions ~11min. Adjust your training intensity in each discipline to hit these targets.
Frequently Asked Questions
Is this triathlon pace calculator free?
Yes, completely free with no signup required.
What are the standard triathlon distances?
Sprint: 750m swim / 20km bike / 5km run. Olympic: 1,500m swim / 40km bike / 10km run. Half-Ironman (70.3): 1.9km swim / 90km bike / 21.1km run. Ironman: 3.86km swim / 180km bike / 42.2km run.
How long does an average Ironman take?
Average age-grouper Ironman finish time: 12–14 hours. Pros finish in 8–9 hours. A sub-12 hour Ironman is a solid goal for most recreational athletes. Cutoff time is 17 hours.
What swim pace is needed for a 1-hour swim split?
For a 1,500m Olympic swim in under 30 minutes, you need a pace of 2:00/100m. For a 1.9km Half-Ironman swim in 45 minutes, pace is 2:22/100m. Train in the pool at your target race pace.
How should I allocate time between events?
As a rough guide for beginners: swimming is typically 10–15% of total time, cycling 50–55%, running 30–35%, plus transitions (T1/T2 add 5–15 minutes total). Elite triathletes swim faster and maintain higher bike/run paces throughout.
