Major Texas event
San Antonio Marathon Weekend
December 4–6, 2026 · San Antonio, Texas · Bexar County
San Antonio Sports confirms the 2026 San Antonio Marathon weekend for December 4-6, with the SATX 5K on Friday and the marathon and half marathon on Sunday. This replaces the supplied seed inventory's obsolete Rock 'n' Roll San Antonio label: the Rock 'n' Roll Running Series left San Antonio after its 2024 event, and the locally organized San Antonio Marathon is now the current signature race weekend.
Why plan around San Antonio Marathon Weekend?
San Antonio Marathon Weekend is the city's current signature distance-running event, pairing a downtown 5K with marathon and half-marathon courses centered on Hemisfair. The locally organized weekend succeeds the former Rock 'n' Roll San Antonio era while keeping a major December running event in the Alamo City.

Plan the visit
Use the current San Antonio Sports schedule
The official race weekend runs December 4-6, 2026. The SATX 5K starts Friday evening, the Health & Fitness Expo runs Friday and Saturday, and the marathon and half marathon start Sunday morning from Hemisfair. Do not rely on older Rock 'n' Roll San Antonio listings when planning this trip.
Choose your race-day logistics before downtown fills
The marathon and half marathon begin at Hemisfair at 7:15 a.m. Sunday. Review the organizer's current course, parking, transit, packet-pickup and road-closure guidance before race weekend, especially if you are staying outside downtown.
Make the weekend part of a San Antonio visit
The downtown start and finish make the race easy to pair with central San Antonio attractions. Give yourself recovery time and avoid scheduling a tightly packed sightseeing day immediately after the marathon if you are racing the full distance.
