Beginner 70.3 & Half Ironman Training Plans

A 70.3 — 1.9km swim, 90km bike, 21.1km run — is a seriously impressive goal. These plans build you up gradually over 24 or 28 weeks, with nutrition strategy and long-session guidance so the distance never feels overwhelming.

24 or 28 weeks — which should I pick?

The 24-week plan is the most popular. The 28-week plan adds a recovery week and suits anyone who wants a gentler build or has a busy period coming up.

Is a 70.3 the same as a half Ironman?

Yes. 70.3 is the total distance in miles; 'half Ironman' is the common name for the same race distance.

Do the plans cover nutrition?

Yes — both 70.3 plans include a nutrition strategy and guidance for long sessions.
