This 12-week intermediate Olympic distance triathlon plan is built for women aged 40+ who want structured, progressive training with a smart balance of performance and recovery. The plan follows a repeating 3-week cycle (2 build weeks + 1 recovery week) to help you gain fitness while managing fatigue, hormones, stress and life load — without burning out.

You’ll train 8-10 sessions per week:
• 3 swims (progressing from 2000m up to ~2500m) with technique focus and purposeful main sets
• 2 main runs each week: one aerobic/base run plus a quality session that progresses from cruise intervals → 1km race-pace reps (from Week 7) → 2km race-pace reps (Weeks 10–11)
• 2 main bikes each week: a weekday turbo interval session plus a longer aerobic ride that later becomes more race-relevant with threshold intervals and short hill repeats (from Week 4)
• Regular brick training to build race-day confidence, alternating between:
o a multiple brick session (threshold-feel repeats of run/bike segments), and
o a sweet spot turbo session with a short Olympic-pace brick run
• Maintenance type strength session a week

Recovery weeks include reduced volume and a consistent pacing benchmark: 10k run time trials, with Week 6 acting as a dedicated recovery + test week to track progress and guide pacing. Week 11 tapers to sharpen freshness, and Week 12 is race week for Olympic distance execution.

Every session includes detailed What / How / Why guidance, plus weekly notes covering female-specific fuelling and hydration, menopause/peri-post considerations, sleep and stress management, niggle/illness adjustments, and mindset prompts to help you train with confidence and consistency.
