Your runway

5 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.

Recover

Fix the nervous system first. Sleep, HRV, and the noise out.

Align

Fit the plan to your actual life, not the one you wish you had.

Condition

Minimum effective dose. The right sessions, done fresh.

Execute

Race-week protocol, pacing, contingency. Nothing new on race day.

Predict your finish time The Ironman training plan

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.

“The hardest thing on this list and the best crowd in world triathlon. You do not race Tenby off a shortcut. Give it a full, patient build.”

Abraham Spring: founder, Unbroken

The race

Ask anyone who has done it: Wales is the one. The town gives itself to the race completely. The swim is a real sea swim with a beach run between laps. The bike never stops climbing, 2,400m of it, much on narrow lanes lined with crowds. The marathon is four laps through town where every athlete's name is on the noise. It is the least PB-friendly and most life-changing race in Britain.
