There’s a lot to like about the San Antonio Rock ‘n’ Roll Marathon, but ideal running weather isn’t one of them. Don’t look for great conditions this Sunday morning either.
Despite the cold front which has swept through Texas this week, temps will be downright toasty on Sunday morning in San Antonio. The forecast is for cloudy conditions with temps in the mid to high 60s at the starting time of 7:30. Once the clouds burn off, it will heat up quickly with a forecast high of 84 degrees.
This will be the sixth year of the race and only in the first edition of San Antonio was the weather ideal. Instead, San Antonio Rock ‘n’ Roll has been plagued with warm, humid weather. Mindful of this, the organizers of the race tried to move the race date to December, but due to a contract with the Dallas Marathon were unable to.
So San Antonio Rock ‘n’ Roll—the largest timed race in Texas with more than 16,000 finishers—will begin on Sunday at a new starting location. Instead of a downtown start, the races will begin right outside the Alamadome at Cherry and Commerce streets. As usual, the marathon and half marathon will finish on Cherry, adjacent to the Alamodome parking lot where all the post-race festivities take place.
Parking is always a problem at the start/finish as there isn’t any parking at the Alamodome lot. Downtown parking is also a mess due to construction. Your best bet is to park at the AT&T Center and take a free shuttle bus to the start, beginning at 4:30 a.m. There are plenty of shuttles after the race back to the AT&T Center.
None of the San Antonio Rock ‘n’ Roll races—a 5-K, half, marathon or two-person relay—have sold out yet. Online registration has closed, but you can still register at the runners expo at the Alamodome on Friday and Saturday.
Expo hours are 11-7 p.m. (Friday) and 9-5 p.m. (Saturday).
