Just a few miles South of the Perimeter Trail are two hidden gems. Rim Runner showcases Franklin State Forest's West Rim and West Side trails (a 20 mile loop) and the Sherwood Forest trail in South Cumberland State Park (2.6 mile loop). This race is happening early in the Spring so we’re able to see through the trees and over the rim of the cove and also so the creeks and waterfalls can be flowing at their best. The 6am race start time is intentional so you get over to the East side of the course for the sunrise and many people (in the 50 and 100 mile ultramarathon distances) will hopefully be on the West side for the sunset.
The course is very runnable. Really cool rim running for many miles. A stone bridge is on the course! A few nice creeks, small bridges and even a waterfall/swimming hole right off the course.
