Course & Elevation

The UTHealth Houston Half Marathon & 10K is a half marathon through downtown Houston, held on a Sunday in late October and presented by the Houston Striders, an all-volunteer non-profit running club. The race start is at the corner of Bagby and Lamar, beside Sam Houston Park, where the runner village is also set up. The organisers describe it as a scenic, mostly flat course, and the event calls itself fast, flat and philanthropic. The half marathon, the handcycle half marathon and a 10K take place on the same morning, with the half marathon starting at 7:00 am. The time limit is four hours, and the organisers describe it as strict. The 19th edition on 25 October 2026 drew more than 8,100 runners, the largest turnout in the event's history, with UTHealth Houston as title sponsor for the fourth year in a row. It should not be confused with the Aramco Houston Half Marathon, which is run in January on the Chevron Houston Marathon weekend.
