Alamo 13.1 Half Marathon

Sunday, March 2, 2025 • San Antonio, TX • Course Map

From the boom of the cannon that starts runners off just south of the site where Davy Crockett, Jim Bowie, William Travis and roughly 200 Texans held off General Santa Anna and his more than 1,000 troops for some 13 days back in 1836, runners will make their way through a number of this city’s best-known historic and cultural sights before coming back to where it all began for a post-race party near the Alamo.

Here in the region known as the Texas Hill Country, the unique and varied landscape — with some areas characterized by sandy topsoil, yucca, cactus and Texas live oak, while others boast wide, green grassy meadows and tree-covered hills — stand in contrast with much of the state’s flatter terrain.

The race route starts and finishes just south of the Alamo, at the Henry Gonzalez Convention Center, and heads north from there, taking runners north past the Alamo before heading south through downtown.

They’ll run past the city’s famed Majestic Theater, built in 1929 and inspired by the architecture of the Spanish Mission and Baroque styles, the onetime movie house today is home to traveling Broadway productions as well as the San Antonio Symphony.

After passing the Majestic Theater, the race continues south of downtown San Antonio, roughly following the route of the San Antonio River. Runners will pass Roosevelt Park and the Riverside Golf Course before reaching the turnaround point at the golf course.

At the turnaround point, the race takes runners north, retracing some of their steps before taking a detour into Concepcion Park and then running along the River Walk all the way back to the finish line.
