San Antonio, United States of America · Friday 4 December 2026
The Rock n Roll San Antonio Marathon in April 2026 offers a straightforward full marathon on trail terrain through relatively flat to gently rolling landscape, making it a solid choice if you're looking to avoid technical footing while still getting some elevation work. The course stays low overall, ranging between 177 and 239 meters above sea level with only 147 meters of elevation gain across the full 42.2 kilometers, so you won't face any surprise climbs. Running in San Antonio in late April means warm temperatures, so prepare accordingly with your hydration and pacing strategy. The trail surface will feel different underfoot than road racing but shouldn't demand serious technical skills given the gentle topography. This is a working marathon from the Rock n Roll series, so expect the standard race logistics and event experience you'd get from that organization, though you'll want to confirm current registration status and race details since the event information available appears incomplete.
