Duathlon training emphasizes run durability and bike threshold power with run-bike-run bricks — because the run legs account for most race time and leg fatigue, bike pacing must stay controlled.
8-week sprint duathlon outline
- 3 runs + 2 bikes per week at peak
- 1 run-bike-run brick every 10 days
- Run intervals on fresh legs; bike sweet spot and threshold
- Taper: reduce run volume 30% final week
Pacing strategy
First run: controlled — 5–10 sec/km slower than standalone 5K pace.
Bike: steady threshold, not max — save legs for run 2.
Second run: accept pace drop; focus on even effort.

Frequently asked questions
Is duathlon harder than triathlon?
Different stress — no swim recovery, but two runs punish the legs. Bike discipline is critical.
How long to train for a sprint duathlon?
6–8 weeks race-specific on top of a run-bike base.
