How to plan your race season
1. Pick an A-race and work backwards
Choose one "A-race" — the event that defines your season. Count back from race day using the suggested prep window on each card (typically 5–9 months for a 70.3, 8–12 months for a full Ironman). Build base fitness first, then race-specific speed and brick work in the final 12 weeks.
2. Add build-up races (B and C races)
Use shorter races to sharpen fitness and rehearse race-day logistics:
- 12–16 weeks out: Sprint or Olympic — test pacing and transitions
- 6–8 weeks out: A 70.3 or middle-distance — rehearse nutrition at race effort
- 2–3 weeks out: Short tune-up only — keep it easy
3. Match the race to the conditions you can train for
A hilly course (St. George, Nice, Lanzarote) demands sustained climbing training. A hot race (Kona, Singapore, Dubai) needs 2–4 weeks of heat acclimation. Cold-water swims (Alcatraz, Norseman, Oceanside) require wetsuit-skill work. Don't pick a race you can't replicate in training.
4. Nail nutrition before you nail splits
The number one reason athletes DNF a 70.3 or Ironman is fuelling, not fitness. Start with our Race Nutrition Planner to get target carbs, sodium, and fluid per hour, then rehearse the plan on every long session.
