Back in 2012, Serbian professional triathlete Bojan Marić ripped off a respectfully fast 8-hour full Ironman Triathlon in Cozumel, Mexico, one of the 14 that he completed in his 15-year triathlon career.
He retired, became a prolific coach, and recently got back into the open water, finishing the 34 km Wörthersee Swim in Austria in 10 hours 58 minutes [see below]. But he wants more.
He recently registered with the Mayan Channel Swim (@mayanchannelswim), a 27 km channel crossing of the Cozumel Channel between the coast of Playa del Carmen and Isla Cozumel off the eastern coast of Mexico in the Caribbean Sea. The beautiful stretch of water, colorful in its sea greens and azul tones, presents a tough 27 km crossing due to its unpredictable currents running 2 knots for up to 8 hours, but that is not enough for Marić.
He will be the first person to attempt El Cruce Doble, a 54 km two-way crossing.


He will be joined by a host of swimmers from around the world:
- Mariia Trunkova of Russia in April 2026
- Laurent Didier of France in May 2026
- Carmen Oseguera of Mexico in May 2026
- Shannon House Keegan of the USA in May 2026
- Kevin Pomaski of the USA in May 2026
- Rich Mann of the USA in May 2026
- James Crabb of the USA in June 2026
- Kathleen Wilson of the USA in June 2026
- Jill Jamieson of the USA in June 2026
- Regan Billingsley of the USA in June 2026
- Edgar Loaiza of Mexico in June 2026
- Patricia Loaiza of Mexico in June 2026
- Pablo Cavazos of Mexico in June 2026
- Samir Kussaba of Mexico in June 2026
- Jorge Juárez of Mexico in June 2026
- Bojan Marić of Serbia in June 2026 to attempt the 54 km El Cruce Doble
The event was envisioned by Mexican marathon swimmers Orlando Iván Mejía Tronco (shown on left below) and Juan Fernando Urrutia Valencia (Mexico, 47, MSF bio here, on right below). Their recommendation: “Know it, respect it, master it.” But they also state, “In the case of the crossing from Cozumel to Riviera Maya, swimming speed is essential. Despite the fact that we always avoid the hours of maximum current, we cannot prevent a certain intensity of drift during the crossing, depending on the tidal coefficients, so we advise maintaining at least 3.5 km per hour for several hours.”
Crossings will begin at 6 am and must be completed within a time range of 7 or 8 hours.
