What swim, bike and run paces do you need for your triathlon goal time?
Set a goal finish time and get the swim, bike and run paces you need — with transition time built in.
Quick answer
Goal-time planning works backwards: target finish − T1 − T2 = athletic time, then split that across swim, bike and run. For a 3:00 Olympic, with 5 min transitions, 175 min remain — a typical age-group split (~11% / 52% / 37%) needs ~1:17/100 m swim, ~31 km/h bike, ~5:25/km run. Change the split strategy if you are bike- or run-strong.
Required swim pace
1:17 /100 m
- Required bike speed
- 26.4 km/h
- Required run pace
- 6:29 /km
- Athletic time (excl. transitions)
- 2h 55′ 00″
Splits allocate the athletic time between swim, bike and run. Adjust the strategy if you are stronger on the bike or run — then check paces against your training data.
How it works
This is a planning model, not a coach — validate paces against recent bricks and a power meter on the bike leg. Nutrition stays simple: practice race-day fueling in training; do not experiment new gels on the start line.
The plan is decided on the bike and paid for on the run. Riding ten or fifteen watts above what the split calls for buys back a minute or two on the bike and routinely costs five to ten on the run — it is the single most common way an age-group race falls apart, and it happens because the bike feels comfortable at the time. Build the bike leg deliberately conservative and let the run be where you spend. And be honest about the transitions: at large races the run from swim exit to the rack can be hundreds of metres, and it belongs in the total.
Frequently asked questions
How does the split strategy work?+
Typical uses format-specific age-group percentages (e.g. Olympic ~11/52/37 swim/bike/run of athletic time). Bike-strong shifts ~8% from run/swim to bike; run-strong does the opposite. Equal splits are educational but rarely match real races.
Can I hit a sub-3 h Olympic with these paces?+
Sub-3 h Olympic needs ~1:10/100 m or faster swim, ~33+ km/h bike and ~4:50/km run after transitions — elite territory. A 3:00 goal with typical splits lands near 1:17 swim, 31 km/h bike, 5:25 run — solid age-group.
70.3 vs Ironman pacing — what changes?+
Longer races use slightly lower bike/run intensities for the same % split — the calculator adjusts distances and default goal times. Ironman run pace is almost always slower per km than 70.3 even for the same athlete.
Should I include nutrition stops in transition time?+
Count only T1/T2 boxes — aid stations on course belong in bike/run pace averages (slower effective speed). Practice eating on the bike so you do not lose minutes standing at the tent.
