Peak Phase Training for Triathletes
The sharpest, most race-specific block before taper
The peak phase is short — usually 2 to 4 weeks. It sits between build and taper. The goal is one last round of high-quality, race-specific work to get you as sharp as possible while volume starts to trend down.
What Peak Means
Peak is not your highest volume. That already happened in build. Peak is about quality: race-pace specificity, transition practice, pacing rehearsal, and getting every system (mental, physical, nutritional) race-ready.
- • Volume: 85–95% of the peak build week
- • Intensity: same or slightly higher than build
- • Specificity: workouts mimic race conditions as closely as possible
- • Recovery: much more intentional — naps, nutrition, sleep
Signature Peak Workouts
Race-simulation brick
Open-water swim at race pace → bike at race power for 60–90% of race distance → short run off the bike. Done once per peak block.
Sharpening intervals
Short, high-quality intervals (e.g., 8 × 2 minutes VO2). Keeps top-end fitness engaged without adding fatigue.
Pacing rehearsals
Long sessions with disciplined pace control — holding goal race pace by power/HR rather than feel.
Full race-gear dress rehearsal
Train in the exact kit, shoes, nutrition, and bottles you'll use on race day. No surprises left.
Rehearse Everything Race-Adjacent
- • Morning routine: wake time, breakfast, pre-race fueling
- • Transitions: time both T1 and T2 on a practice course
- • Nutrition: rehearse exact race-day intake on long sessions
- • Mental prep: visualise each leg and the handoffs
- • Plan B: what happens if the swim is rough? Flat tire? Heat? Write it down
Avoid These Peak-Phase Traps
Chasing last-minute fitness
You can't build new fitness in 2 weeks. Trying to will only dig you into a hole. Trust the work already done.
Ignoring recovery signals
A stale peak week is a red flag, not a badge. Cut a workout before adding one. Going into taper under-recovered costs more than it gains.
Trying new gear or nutrition
Peak phase is a freeze. New shoes, new gels, new drinks — all deferred until after the race.
