Ten months after setting a Guinness World Record with his open-water swim around Manhattan, David Olvera has rewritten the record books again — this time by swimming from Cozumel to Cancún.
Olvera, 31, from Ciudad Valles, San Luis Potosí, swam the 85 kilometers (about 53 miles) on Tuesday, completing the crossing in 16 hours, 48 minutes of nonstop swimming.
The feat set a new record for the longest solo, unassisted, open-water swim in Mexico, surpassing the previous widely recognized 55-kilometer record held by Graco Morlán.
Olvera set out in the early hours of the morning off Cozumel and faced strong currents, humid Caribbean conditions and the physical toll of nearly 17 hours in the water.
The marathon crossing was officially documented — including video of his arrival in Cancún — with observers on hand to comply with validation protocols for the national record, according to media reports.
One Facebook account posted, “¡Orgullo potosino!” — which means “Potosí Pride!”
On Instagram, a small hotel in Cozumel posted, “Not every achievement is measured in numbers, some are felt in discipline, focus, and the strength to keep going when it matters most. Congratulations to David Olvera … a truly historic accomplishment [and an] inspiring reminder of what happens when preparation meets determination.”
The swim capped a years-long pursuit for Olvera, who has over 15 years of experience as a high-performance swimmer.
Published reports said this crossing was his third attempt at the 85-kilometer Cozumel–Cancún challenge. (The world record for the longest unassisted ocean swim is 142.3 kilometers, set in 2024 by Neil Agius of Malta over 60 hours and 35 minutes.)
In June of last year, Olvera completed the 20 Bridges circumnavigation of Manhattan Island in 5 hours, 34 minutes, 58 seconds. He covered the 48.5 kilometers in what was recognized by Guinness World Records as the fastest circumnavigation swim around Manhattan — beating the existing mark by nearly seven minutes.
Upon his arrival in Cancún Tuesday, Olvera was welcomed by Cancún Mayor Ana Paty Peralta, who presented him with an award and said his achievement was a point of pride for the country. Shortly after he stepped onshore, exhausted, someone draped the Mexican flag across his shoulders.
Olvera has said the Cozumel–Cancún crossing is another step in a still-evolving career. He is eyeing future ultra-distance challenges abroad, including attempts to cross the Strait of Gibraltar, the English Channel and the Catalina Channel in Southern California.
After his feat this week, the popular Facebook page “Mexican Problems” — which posts Mexico-related viral content, memes and other content — offered its praises to the Potosí iron man.
“David Olvera didn’t do this in a pool with perfect conditions and a cheering crowd every 50 meters. He did it in the open Caribbean Sea — battling currents, waves, darkness, and exhaustion for nearly 17 hours straight,” the post read. “That is the Mexican spirit in its purest form. Not for fame. Not for money. Just to prove it could be done.”
