Your runway

49 weeks to race day: base season

Plenty of runway. This far out, the win is a boring, consistent base rhythm: aerobic volume, strength, technique. The structured block starts closer in; what you do now decides how high it can climb.

Recover
Consider recovery context, sleep and readiness before adding training load.

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

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.

Road to Race

Build my complete road.

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 flat, fast roads, so pacing discipline and aero position matter more than climbing strength. The four-lap run past the marketplace gives plenty of spectator contact.”
