The 70.3 challenge
A step up, done right.
The Half Ironman is a demanding distance - long enough to reward real endurance, short enough to race hard. Your plan respects the distance and respects your life: built around your schedule, your fitness and the specific demands of your race course, then adapted as you go.
What's included
- A fully periodised plan from today until race day, phased across Base, Build, Peak and Taper.
- Structured swim, bike, run, strength and mobility sessions with warm-up, main set and cool-down.
- Race-specific brick sessions to sharpen your run off the bike.
- Personalised nutrition and fueling targets for long sessions.
- Live fitness, fatigue and readiness tracking as race day approaches.
- Move, skip or swap any session yourself. Built on Dean and Richard's coaching.
- Optional Strava sync and Zwift export for indoor sessions.
Phased to peak on race day
1. Base

2. Build
Add race-specific intensity and longer bricks to raise your threshold.
3. Peak
Sharpen with race-pace work and open-water confidence, dialling back volume.
4. Taper
Reduce load to arrive rested, sharp and ready on race day.
