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.

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

Fit the plan to your actual life, not the one you wish you had.
C
Condition
Minimum effective dose. The right sessions, done fresh.

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

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.

Abraham Spring, founder of Unbroken

“The Baltic is properly cold, so do some genuine cold water swimming before you go. The finish through the medieval old town is worth the trip on its own.”

The race

Tallinn is the one people come back raving about. The swim is genuinely cold Baltic water, which is the main thing to prepare for. The bike is flat along the coast. The run threads into the walled medieval old town, and finishing on cobbles inside a UNESCO world heritage site is a rare thing in triathlon. Cheap to reach and easy to make a long weekend of.
