IRONMAN 70.3 Valdivia 2026
A 70.3 at Valdivia in southern Chile: a swim in the Calle-Calle River and a bike through green countryside starting beside the Tres Marías airfield.
8 weeks to race day: a full block fits
This is the sweet spot. A complete 12-week recovery-led build fits inside the runway with room for a base phase in front. Anchor the block to race day and every week between now and then has a reason.
Building for this one? 70.3 training plan covers the sessions, the weekly shape and how the block is paced. The R.A.C.E. Framework explains why it is built that way.
Adapt my training to this course.
Commit to the date and the work gets a shape: your countdown starts, the emails arrive in step with your build, and the app anchors a recovery-led block so the final week lands exactly on race day.
One confirmation email, then the road begins. Registering for the race itself stays with the organiser.
“A river swim means current can matter, so practise sighting and a steady stroke in moving water. The 70.3 shares its date with the full-distance race, so expect a busy course day.”
