San Antonio Marathon Lands Nike as Official Partner for Its Inaugural Run December 4-6

San Antonio Sports has announced a multi-year sponsorship agreement designating Nike as the official athletic brand partner for the inaugural San Antonio Marathon, scheduled for December 4-6, 2026, according to a report read in full by the Sports Desk this cycle.

Under the agreement, Nike will provide technical apparel for thousands of registered runners, host community training sessions along the River Walk, and sponsor youth fun-runs connected to the race weekend, the report said.

Race organizers noted that establishing a premier, world-class road marathon elevates San Antonio's athletic profile on the global marathon circuit. The December dates put the new race at the start of the city's winter events calendar, with the River Walk training sessions beginning in the run-up to race weekend.

The announcement was the civic-wellness item in the same report that carried UT Health San Antonio's 11th Annual Combat PTSD Conference at the Westin Riverwalk. No course route, field size beyond the thousands of registered runners the report described, or registration details were stated in the report, and the desk does not add them here.
