IRONMAN Portugal-Cascais 2026
A full-distance race at Cascais: a swim in Cascais Bay, a two-loop bike along the coast and through the Sintra-Cascais park, and a three-loop run to Cabo Raso and back.
2 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? Ironman 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.
Build my pacing and preparation plan.
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 bike is two loops along the coast and through the Sintra-Cascais park, and the organiser publishes no elevation figure, so check the route map for climbing. The run is three loops along the coast road to Cabo Raso and back.”
The race
