Swim course

The swim will be a rolling start. Athletes will enter the water in a continuous stream through a controlled access point, similar to how running road races are started. An athlete’s times will start when they cross timing mats at the start line. Athletes will be directed to self-seed on race morning based on their projected swim time. Volunteers and staff will be in the staging area with signs and will assist with this process. Self-seeding will not be mandatory but will be encouraged.

Bike course

The bike course is flat and paved, starts at the CHANKANAAB parking lot (T1), and finishes at T2 next to Cozumel’s City Hall in the heart of downtown. Athletes will have to complete 1.3 laps along the highway around the Island in a counter-clockwise direction.

Run course

The 2 lap run course is all flat and paved, it passes many of Cozumel’s signature sites, including its waterfront walk, downtown main plaza, and historic neighborhoods.
