Course, cutoffs and the 50/50 Challenge

The course is single-track trail through wooded, undulating terrain. Trails are described as non-technical with short hills that usually take less than a few minutes to climb. The 50K uses two 13.2-mile loops plus one 5.2-mile loop. The half consists of one loop. Aid stations are on course and are described as accessible by family and friends.

Cutoffs listed are: 50K - 9 hours; 13.2 - 5 hours; 50/50 - 9 hours strict. For the 50/50 Challenge, runners may opt to continue after finishing the 50K to attempt 50 miles, but they must complete the 50 miles within the 50K 9-hour cutoff. Failure to do so results in no credit for either distance. Successful finishers of the challenge receive a shirt and free entry to the following year.
