Your runway
28 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.
“The organiser has not yet published the bike or run route, so check the official page for the course before planning pacing.”

What distances can I race at IRONMAN South Africa?
Full (iron distance). Pick the distance that fits your training runway, not your ego: the right distance is the one you can arrive at fresh.
How hard is the course?
Not yet published terrain, not yet published profile. The organiser does not state a course profile or elevation gain
What is the swim like?
Sea swim at Mossel Bay.. Wetsuit-legal at 24.5°C (76.1°F) or colder, up to 5 mm thick; prohibited above 24.5°C (organiser rule). Practise open water before race week, not during it.
How long do I need to train for it?
Race day is 18 April 2027. For the full distance, a proper recovery-led build wants about 20 weeks, which means starting around 29 November 2026. Later starts still work: the block compresses honestly rather than pretending, and it always anchors to the exact race date.
