Fields of Gold Trail Run

Fields of Gold Trail Run takes place at Shaffer Bend Recreation Area in Marble Falls, Texas. The course uses rolling hills, meadow trails, and lakeside paths and is scheduled to coincide with peak fall color when native grasses and trees display autumn tones.

Distances and formats offered include:

  • 50 Mile
  • 50K
  • Marathon (26.2 miles)
  • Half Marathon (13.1 miles)
  • Half Marathon Ruck division with minimum pack weight rules
  • 12-Hour Endurance Challenge
  • 10K
  • 5K morning and night options

The 12-Hour Endurance Challenge is scored by total miles covered rather than a fixed distance. In the final hour, runners remaining on the course move from the main loop to a designated short basecamp loop to accumulate final mileage; loops must be completed before the event clock stops to count.

The Half-Marathon Ruck is the same trail as the runners but scored and awarded separately. Minimum pack weights are required based on body weight, the load must be secured and carried for the whole course, and water does not count toward the minimum. Packs are weighed and tagged before the race and checked again at the finish.

Aid stations provide seasonal items such as apple cider and pumpkin cookie bites. Registration benefits Healthy Kids Running Series Cedar Park youth programs. Participants receive a finisher medal, race shirt, and access to a post-race harvest celebration. Trail routes may be adjusted for weather or to protect natural areas.
