With the roads closed most of the day, this is not the day for the island loop. Take the water instead — a morning dive or snorkel on the reefs — and give the evening to the finish line downtown, which is worth seeing even if you did not come for it. Check the organiser's closures before planning anything on wheels. advice

Where are the crowds in Cozumel during IRONMAN Cozumel?
The island's roads are closed for most of the day for the bike loops, and downtown is the run course and the finish, through the day and on into the night — the island is in race mode from dawn to the last finisher. Athletes and supporters fill the hotels for the whole of race week.
Road closures: what closes and when the streets reopen
