Texas > Hero-Thon Half Marathon
San Antonio, TX  •  Sunday, January 27, 2013  •  Course Map


With a course that features only a handful of significant hills throughout its 13.1 miles, San Antonio's all-new Hero-Thon Half Marathon Series makes its inaugural running on the last weekend in January 2013, along a counter-clockwise route through the city that starts and finishes at the Alamodome, the home of basketball's San Antonio Spurs.

The race will be open to both runners and walkers and is closely affiliated with the Leukemia and Lymphoma Society's Team in Training program, which helps raise money for the charitable foundation's research and treatment programs to fight leukemia, lymphoma, Hodgkin's disease and myeloma. Organizers are calling the event the "Hero-Thon" to encourage every runner to tap into their own inner "superhero," which they certainly are to every cancer patient and their family who benefits from LLS's work.

Runners and walkers are set to start the race in the parking lot of the Alamodome, which lies near the intersection of Cesar E. Chavez Boulevard and Cherry Street. From there, the course heads south and west in the direction of HemisFair Park, and then north along the I-37 Access Road around the Alamodome to Cherry Street, where they'll turn left and head north.

After a left turn on Nolan Street, runners head west and into downtown San Antonio. The turn left onto Avenue E will bring them south to the Alamo itself, the famed site of the pivotal 1836 Battle of the Alamo that helped turn the tide and end the Texas Revolution later that year. Following the run past the Alamo, the course then turns right twice and heads north toward Brackenridge Park Golf Course, and then west along Ashby Place toward the campus of San Antonio College, the stretch that features the biggest hill of the race.

Once runners make it past the mile 6 marker, they're on the down side of the hill, and the course heads south through San Pedro Park. That's followed by a long southward stretch along Flores Street, which brings runners down to the San Antonio River and the stretch of the race that unfolds along the city's scenic RiverWalk, whose stone and tiled streets are filled with quaint shops and restaurants as well as gondolas passing by on the river.

The course crosses over the river on Lone Star Boulevard, taking runners and walkers along an out-and-back stretch before heading back over the river and back up to Carolina Street. There, the race hits its home stretch, and leads back north toward the Alamodome for the race finish.
