Houston 25K 2026

The Houston 25K begins at 7 a.m. in downtown Houston, offering marathon trainees a long late-fall checkpoint before the Houston Marathon. This is the third event in the Houston Marathon Warm-Up Series, which progresses through the Space City 10-Miler, UTHealth Houston Half Marathon, Houston 25K, and Coach Andy Stewart's 30K. The event also provides 10-mile and 5K options, with in-person and virtual entries available. The field is limited to 1,000 participants. The race is centered around Sam Houston Park and Wortham Center's Fish Plaza, the location for the post-race gathering. HMSA organizes the event for participants of all ages and paces, catering to both competitive age-group runners and those using the distance for training. The 25K awards the top three overall male and female finishers, the top three masters male and female finishers, and the top three finishers in five-year age groups. All finishers receive medals, and participants receive a long-sleeve shirt at packet pickup. The policies of no race-day registration, no transfers, and no deferrals require advance planning.
