Fields of Gold Trail Run takes place in the fall at Shaffer Bend Recreation Area in Marble Falls, Texas, within the Texas Hill Country. The series offers runners a wide selection of distances: 50K, marathon, half marathon, a 12-hour endurance challenge, a 1-hour Gold Hour challenge, 10K, and 5K. The course is designed with dirt and park terrain, featuring rolling hills, meadow trails, lakeside paths, golden grasslands, wooded valleys, and overlooks across the bend area.
The longer races cover the most varied terrain. The half marathon is presented as challenging yet accessible for runners not aiming for an ultra distance. The 12-hour event focuses on total miles accumulated rather than a set finish time, with aid stations and support available throughout the day. The 1-hour race applies the same endurance concept in a condensed format. The 5K Harvest Fun Run serves as the family-friendly option, winding through the meadows. The event also supports HKRS Cedar Park Youth Running Programs, connecting race day activities with local youth running initiatives.
