Alamo Run Fest Half Marathon, 10K & 5K

Sunday, March 17, 2019 • San Antonio, TX • Course Map

runsignup-blueRunners will cross the finish line of this half marathon race inside the arena known as the Alamodome — on the same floor where the NBA’s San Antonio Spurs play — at the Alamo Run Fest Half Marathon, 10K and 5K, which makes its 7th annual running in 2019 in the Texas Hill Country.

The race follows a point-to-point loop route around the city, starting along Cesar E. Chavez Boulevard and then heading north along Cherry Street. From there, the course makes a counter-clockwise loop through the city, taking runners through downtown San Antonio and twice across the river, and past several of its signature landmarks.

During the race, which reaches its hilliest stretches around the middle few miles, runners also make their way through Fairchild Park and past the San Antonio National Cemetery, Roosevelt Park and the campus of San Antonio College before turning into the parking lot of the Alamodome, where they’ll cross the race finish line inside the arena.

Open to both runners and walkers, the race features some rolling hills here and there but otherwise is mostly pretty gentle on the legs. The course time limit will be 4 hours, 15 minutes, which means runners and walkers will need to keep a pace of 19 minutes per mile (or faster) — otherwise, you’ll have to jump aboard the Sag vehicle around the mile 9 marker.

The half marathon will be USATF (USA Track and Field) certified, and it will be limited to the first 4,800 entrants.

    Hi! I registered last year and then realized, several weeks before, that I would not be able to attend. Very graciously, you all offered me an opportunity to use my entry for this year, which I intend to do. I have the note from Porscha Pressler, dated January 21, 2014, but I’m not sure how I go about registering, since if I did the online registration, it would require me going through the payment screen. Planning to book my airplane ticket from Dallas-Fort Worth soon, so let me know how I proceed in registering. Thanks so much and I look forward to coming to San Antonio for your 2015 Alamofest!
