Swim time
15 × 2 min/100 m = 30 min - 2
Bike time
40 km ÷ 28 km/h × 60 = 85.7 min - 3
Run time
10 km × 5.5 min/km = 55 min - 4

How does this calculator work?
Finish time = Swim time + T1 + Bike time + T2 + Run time, calculated from your pace/speed for each discipline. Typical age-group averages (2024 estimates): Sprint ≈80 min, Olympic ≈165 min, 70.3 ≈360 min, Ironman ≈780 min. Enter your paces and transitions to get your personalised split breakdown.
Formula
How this is calculated
Each triathlon segment is calculated separately: swim time equals the swim distance in 100-metre blocks multiplied by your pace per 100 m; bike time equals the bike distance divided by your average speed in km/h and converted to minutes; run time equals the run distance multiplied by your pace per kilometre. The two transitions (T1: swim-to-bike; T2: bike-to-run) are added as flat time estimates.
The typical average finish times shown (Sprint ≈80 min, Olympic ≈165 min, Half-Ironman ≈360 min, Ironman ≈780 min) are approximate medians for adult age-group finishers drawn from published race results aggregated around 2024. They vary noticeably by race course, weather, gender and age group — treat them as a rough benchmark, not a precise standard.
For planning purposes, note that open-water swim pace is typically 5–15% slower than pool pace due to navigation and waves; bike speed on a hilly or point-to-point course differs from training averages; and most athletes run 10–30% slower in a triathlon than in a standalone race because of accumulated fatigue. Adjust your inputs conservatively for race-day prediction.
Frequently asked questions
For adult age-group finishers the median full Ironman finish time is roughly 12–14 hours, depending on the course and conditions. Elite professionals finish in 7.5–9 hours. The cutoff time enforced at most Ironman events is 17 hours.
Most swimmers are 5–15% slower in open water due to lack of lane ropes, turns, navigation sighting and potential choppiness. A 1:45 per 100 m pool swimmer might expect 1:55–2:00 per 100 m in a race. Add a buffer and practise open-water swimming before race day.
Sprint and Olympic triathlons typically see T1 of 1–4 minutes and T2 of 1–3 minutes for age-groupers. Half-Ironman and Ironman transitions run longer (3–8 minutes each) because athletes may put on additional clothing or apply sunscreen in a changing tent. The calculator defaults to 3 min and 2 min — adjust to match your race.
