Triathlon swim training needs 2–3 pool sessions per week minimum — technique drills, steady aerobic sets, and occasional open water practice — because swim fitness drops faster than bike or run when frequency is low.
Weekly swim structure
- 2–3 swims × 30–45 min for sprint/Olympic
- 3–4 swims × 45–60 min for 70.3 and Ironman
- 1 technique-focused session with drills each week
Open water skills
Sight every 6–8 strokes, practice drafting and buoy turns, and swim in a wetsuit before race day.
Using Vo2Max
Vo2Max allocates swim sessions across your week so frequency stays consistent through build and peak.
