Total leg time = Swim time + Bike time + Run timeSwim pace /100m = Swim time ÷ (Swim meters ÷ 100)Bike km/h = Bike km ÷ (Bike time in hours)Run pace /km = Run time ÷ Run km| Format | Swim | Bike | Run | Total km |
|---|---|---|---|---|
| Sprint | 750 m | 20 km | 5 km | 25.75 |
| Olympic | 1.5 km (1500 m) | 40 km | 10 km | 51.50 |
| Half Ironman (70.3) | 1.9 km | 90 km | 21.1 km (half marathon) | 113.00 |
| Ironman (140.6) | 3.8 km | 180 km | 42.195 km (marathon) | 226.00 |
| Phase | Typical range | Planning note |
|---|---|---|
| T1 (swim → bike) | 2–5 min | Wetsuit peel and mount line add time; fast AG athletes often 2–3 min. |
| T2 (bike → run) | 1–3 min | Shoes, nutrition, and rack position matter; add to run leg for conservative totals. |
| Sprint total T1+T2 | 3–6 min | Example: 1:17:00 legs + 5 min transitions ≈ 1:22 race clock. |
| Olympic total T1+T2 | 4–8 min | Sub-2:30 Olympic plans often budget ~5–7 min transitions on top of 2:30 leg sum. |
| 70.3 / Ironman | 8–15+ min | Long-course transitions are larger; Ironman can exceed 10 min combined in crowded races. |
30:00 + 1:10:00 + 50:00 = 2:30:00 · 2:00 /100m · 34.29 km/h · 5:00 /km · bike 46.7% of leg time
12:00 + 40:00 + 25:00 = 1:17:00 · 1:36 /100m · 30.00 km/h · 5:00 /km
35:00 + 1:25:00 + 1:00:00 = 3:00:00 · 2:20 /100m · 28.24 km/h · 6:00 /km
35:00 + 3:15:00 + 2:05:00 = 5:55:00 · bike 54.9% of day
1:15:00 + 6:30:00 + 4:30:00 = 12:15:00 · run 6:23 /km on 42.195 km
