Flatrock | Georgia

Flatrock | Georgia is held in Dacula, Georgia, on October 17, 2026, organized by Wolf Peak Outdoors. Three trail formats are on offer: a half marathon (13.1 miles), a 50K (31 miles), and the 50/50 Challenge, which combines them into 50 miles (80.5 km) of running in a single day.

The tiered structure makes the choice straightforward. If you already race road half marathons, the trail half is a comfortable move onto dirt. If you have a marathon behind you, the 50K is the classic first ultra and a realistic target on a 16-week plan. The 50-mile challenge is a genuine ultra day that deserves back-to-back long runs on the weekends, a fueling plan you have tested in training, and a willingness to walk the climbs early rather than paying for them in the last ten miles.
