Flatrock Trail Run

Flatrock is scheduled for October 17, 2026 in Dacula, Georgia. All races begin and end at Harbins Park main entrance by the pavilion at 2995 Luke Edwards Rd, Dacula, GA 30019.

The event includes these distances:

  • Half Marathon
  • 50K
  • 50/50 Challenge

The course uses mixed-use trails with rolling hills and mostly tree coverage. Trails are not highly technical by most standards but require attention to footing for roots, rocks, and holes. There are a few short stretches of pavement. The route is marked with ground flagging and directional signage; flagging is pink for the 5.71 mile pink loop and blue for the 7 mile blue loop. Runners return to a central aid station roughly every 6 to 7 miles. Aid station provisions include electrolyte mix and typical ultra race fare. Detailed maps and GPX files are provided for navigation.

This is a cupless race; a hydration container is required to obtain liquids. A phone is required for emergencies. Cutoffs are set at 5 hours for the Half Marathon and 9 hours for both the 50K and the 50/50 Challenge. Parking is available at the main lot with an overflow dirt lot. There is no on-site camping; nearby lodging options include Fort Yargo State Park and a Holiday Inn Express in Bethlehem, GA. In emergencies dial 911. The race may be delayed or canceled in severe weather. Visit the organization's website for the most recent information.
