WHATABURGER ‘WHATARUN 5K/10K’ (San Antonio, TX)

WHATABURGER ‘WHATARUN 5K/10K’ takes place in San Antonio, Texas, on November 21, 2026. Two road distances are offered: the WHATA 10K (6.2 miles) starts at 8:30 a.m., and the WHATA 5K (3.1 miles) follows five minutes later at 8:35 a.m. The event carries the Whataburger name, which gives it a distinctly Texan brand identity.

The two-distance format lets you pick your challenge. The 10K is the option if you want a real test of fitness: eight weeks of training with a weekly longer run building to 7 miles and one session of steady tempo running will set you up well. The 5K suits newer runners or anyone who wants a quick, sharp effort before the holidays. Because the starts are only five minutes apart, warm up early and make sure you are lined up for the right event. For the 10K, run the first two miles at a pace that feels slightly too easy; the distance rewards restraint early and a strong second half.
