IRONMAN Cozumel 2026
A clear Caribbean non-wetsuit swim over reef, three flat laps of the island, and a flat run finishing in the downtown plaza.
14 weeks to race day: a full block fits
This is the sweet spot. A complete 12-week recovery-led build fits inside the runway with room for a base phase in front. Anchor the block to race day and every week between now and then has a reason.
Building for this one? Ironman training plan covers the sessions, the weekly shape and how the block is paced. The R.A.C.E. Framework explains why it is built that way.
Start my Road to IRONMAN Cozumel.
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.
“Twenty-six degree water means no wetsuit and no buoyancy, and twenty-nine degree air means the run is a heat management problem. If you cannot swim 3.8km without neoprene, this is not the race to find that out at.”
The race
The course
No course maps for this race. IRONMAN publishes no downloadable route for any leg of this race, only a live tracker that runs on race day, so there is nothing to draw a course map from. Everything below comes from the official course page, checked on the date at the foot of this section.
Clear Caribbean water with visible reef life below you the whole way, and at 26-28°C it is almost always non-wetsuit. The official page describes the swim without ever stating the lap count, so we do not state one either.
Three laps of the island, taking in the ocean road, the hotel zone and part of the town. Flat and fast on paper, but the windward side of the island is fully exposed and the crosswind on each lap is the thing people remember.
Flat, through the waterfront walk, the downtown plaza and the older neighbourhoods, finishing at the City Hall plaza. The official page does not state a lap count for this leg.
Not yet confirmed for this edition: swim lap count, run lap count, transition locations, cut-off times, water temperature history. We publish these only once they are on the official course page, so check there before you pace off anything here.
