37 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 12-week block starts later; what you do now decides how high it can climb.

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

Building for this one? Training plans cover 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 race

London is the race that turns runners into marathoners. Entry is by ballot, charity place or championship time, and demand outstrips places many times over. The course is flat and fast, Cutty Sark and Tower Bridge lift you when it hurts, and the last miles down the Embankment to The Mall are the loudest in world running. If the ballot lands, everything else in your season moves aside.
