San Antonio Marathon Set to Launch in December 2025

San Antonio Sports and the City of San Antonio have announced the launch of the San Antonio Marathon, set for December 7, 2025.

The marathon will follow The Running Event, North America’s largest running convention, December 2–4. San Antonio Marathon weekend extends TRE with an expo on December 5–6, followed by the marathon on December 7. The event will succeed the Rock ‘n’ Roll San Antonio Marathon which has taken place for 16 years.

“We’re excited that The Running Event will bring the running industry to San Antonio, followed by a world-class destination marathon,” said Jenny Carnes, president and chief executive officer of San Antonio Sports. “Participants will get to experience a course that’s uniquely San Antonio along with the festive spirit of our downtown during the holidays. There’s no more beautiful time or better place to run.”

Organizers expect to draw more than 18,000 runners and walkers who will experience a course showcasing San Antonio’s spirit, culture and heritage. The Trust Group will manage the San Antonio Marathon, while professional runner and Olympian Meb Keflezighi will provide insights in designing a Boston Marathon-qualifying course.

The course will feature themed miles, including the Yanaguana Mile, Fiesta Mile, Military Mile, Rodeo Mile and Culinary Mile. San Antonio Sports is also collaborating with Centro San Antonio and Visit San Antonio to ensure a successful experience for downtown businesses and visitors.

“We have created a strong marathon tradition over the years and the new San Antonio Marathon will enhance the city’s stature with runners, helping solidify our race as a destination marathon in the tradition of New York and Boston,” said Mayor Ron Nirenberg. “This change will benefit our community as well marathon enthusiasts.”
