Alamo 13.1 Half Marathon

Sunday, March 4, 2018 • San Antonio, TX • Course Map

From the boom of the cannon that starts runners off from the site where Davy Crockett, Jim Bowie, William Travis and roughly 200 Texians 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 at 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 at the Alamo and heads north from there, taking runners first 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.

Alamo St. At the 1 mile mark, the course takes a right onto Mccullough Ave, which turns into Nolan St. past 37. Runners continue to make their way through the city for the next 3 miles until the 6 mile mark where they start to head north into the park.


Runners will make their way onto Lions Field Trail which will take them to the right of Brackenridge Park. Past the 7 mile mark, the course takes runners onto Tuleta Dr for the next mile as the make their way around the water next to the San Antonio Zoo. Turning right onto Brackenridge Dr, heading south to the 9 mile mark.
