Challenge Vieux Boucau 2026
A middle-distance triathlon at Vieux-Boucau: one swim loop in the marine lake, a mostly flat bike in the Landes and a four-lap run.
1 weeks to race day: the sharpening window
A full build no longer fits, but a sharp one does. This close in, the job is specificity and freshness: race-pace touches, open-water or brick rehearsal, and a taper your nervous system actually absorbs. No heroics; arrive fresh.
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.

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.
“The organiser describes a mostly flat single-loop bike and a four-lap run with aid at km 2 and km 4 of each lap, so plan your fuelling around those stations.”
