Your runway
42 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.
R
Recover
Consider recovery context, sleep and readiness before adding training load.
A
Align
Fit the plan to your actual life, not the one you wish you had.
C
Condition
Minimum effective dose. The right sessions, done fresh.
E
Execute
Race-week protocol, pacing, contingency. Nothing new on race day.
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.
“Plan around the start times: the organiser lists the Olympic at 8:20 AM and the Sprint at 9:40 AM. The organiser notes waves are already selling out, so decide on your distance early; relay entries are offered if you want a team format.”
