Your runway

30 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.

Road to Race

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.

Abraham Spring, founder of Unbroken

“The bike is two laps through rolling countryside and the run is three laps around the Regatta Centre, so plan fuelling around the loops. The organiser publishes no elevation figure.”
