This Sunday, March 2, the municipality of Coamo will hold the 63rd edition of its traditional race, with 3,100 registered runners.
Walking the streets of the municipality of Coamo just days before the Medio Maratón San Blas 2025 is like breathing an air of celebration, enthusiasm and passion for sport, and that passion is shared by Puerto Rican runners, world-class athletes, merchants, residents and Puerto Ricans in the diaspora who, as in past years, will return to the town where they were born to enjoy and take in its unchanged culture.
This Sunday, March 2, at 7:00 a.m., the starting gun will fire for the 3,100 participants who will set off from highway PR-14, in the Las Calabazas sector, to take on the famous San Blas route.
