Mustang Marathon (Hill Country Trivium Road Race)

Mustang Marathon (Hill Country Trivium Road Race) takes place in Marble Falls, Texas, on November 8, 2026, organized by Perspective Pacing. The 50K (31 miles), marathon (26.2 miles) and half marathon (13.1 miles) all start at 7:00 AM, followed by the 10K at 8:00 AM, the 5K at 8:30 AM and a youth 1-mile run for kids 12 and under at 9:30 AM.

With six distances on one morning, this event fits nearly every runner in a family or club, from a first-time kid to an experienced ultrarunner. Whether you take on the 50K or the marathon, the Texas Hill Country is aptly named, so make hill repeats and long rolling runs a regular part of a 16- to 20-week build. The half marathon and 10K are good goals for runners who want a scenic fall race, and the early November date usually keeps the heat manageable compared with summer.
