David Olvera, a 31-year-old swimmer from San Luis Potosí, has broken the record books by swimming nonstop from Cozumel to Cancún, setting a new record for the longest solo, unassisted, open-water swim in Mexico. The feat was completed in 16 hours, 48 minutes, surpassing the previous 55-kilometer record held by Graco Morlán. The crossing was officially documented with observers on hand to comply with validation protocols for the national record. The swim marks the third attempt at the 85 kilometer challenge and marks the end of a years-long swimmer's quest to achieve this feat.
