About the ROC 7K Trail Run Course:

Rhett’s Run is a single track trail designed for mountain biking. It also makes  a great running trail because it is well maintained and includes just the right amount of varying terrain to make it fun. Along the 4.3 mile course, ROC runners will encounter some hills, rocks, roots, grass and the occasional bit of gravel. It’s beautiful out there! The course will be very well marked with flagging in trees, arrow signs and kilometer markings, as well as volunteer support. There will be one aid station with volunteers, water and light first aid supplies.
