Your runway
50 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. Joining this Road does not request priority access; use the organiser link for that.
“The organiser describes a hilly bike into the mountains followed by a run at sea level, so rehearse running off a climbing bike leg. The 24-27°C air temperature the organiser lists is mild, but fuel and hydrate on schedule across 80 km of bike.”
Abraham Spring: founder, Unbroken

What is the swim like?
Sea swim off Marbella's beaches; the organiser lists average water temperature of 23-24°C. Not stated by the organiser. Practise open water before race week, not during it.
How long do I need to train for it?
Race day is 18 – 19 September 2027. For T100's 2 km swim, 80 km bike and 18 km run, a proper recovery-led build wants about 12 weeks, which means starting around 26 June 2027.
