Flatrock, Dacula, Georgia
Flatrock is a trail running event held in Harbins Park near Dacula, Georgia. Races take place on flowing singletrack through wooded terrain with undulating hills. The trails are described as nontechnical but require map reading, attention, and following course markings.
Distances offered:
- 50K
- Half Marathon (13.1 miles)
- 50/50 Challenge
The 50K course uses two 13.2 mile loops plus one 5.2 mile loop. The half marathon consists of a single loop. Aid stations are located on the course and are accessible to friends and family near the route and start/finish area.
Time limits and rules are specified for each distance. Known cutoffs include a 9 hour limit for the 50K and a 5 hour limit for the 13.2 mile loop. The 50/50 Challenge requires completing 50 miles within the 50K 9 hour cutoff; failing to do so results in no credit for either distance.
