San Antonio, United States · Sunday 2 March 2025
San Antonio's Run The Alamo marathon takes runners through the heart of a city steeped in American history. The course winds past The Alamo itself, along the tree-lined streets of the King William district, and through the UNESCO World Heritage Missions that dot the landscape. Runners will pass the San Fernando Cathedral, historic Houston Street, and the famous River Walk, experiencing the Alamo City's character and charm firsthand. The race kicks off with a sunrise cannon blast and musket volleys to set the tone, immersing participants in the region's frontier heritage while they run. The course is a flat to gently rolling trail route through downtown and along San Antonio's cultural corridors, with modest elevation changes that barely exceed 50 meters across the entire marathon. At this altitude, ranging between 154 and 198 meters above sea level, runners won't face the adjustment demands of high-elevation racing. The terrain is straightforward and runnable, allowing you to focus on the historic sights around you rather than managing steep climbs or technical footing. It's the kind of course where you can maintain a steady effort while taking in your surroundings, making it well-suited for runners who want a solid marathon experience without serious elevation concerns.
