About
The San Antonio Marathon debuted in December 2025 as a locally organized replacement for the former Rock 'n' Roll San Antonio. Owned and operated by nonprofit San Antonio Sports, in partnership with the City of San Antonio, the inaugural event drew a sold-out crowd of over 18,000 participants from every U. S. state and 25 countries. The USATF-certified course starts at Main Plaza and finishes at Hemisfair, running through the city's most iconic neighborhoods.
