Course and logistics
The course uses a loop of 16.7 km (10.35 mi). Distances are completed by repeating loops: 100K = 6 loops, 50K = 3 loops, 20 Mile = 2 loops, 10 Mile = 1 loop, and the 5K follows the first portion of the course. The event has a 15-hour cutoff for the full course.
Aid stations are located at the start/finish and near mile 5, and they offer water, electrolyte drink, pretzels, candy, PB&J, salt tabs, and other items. Drop bags may be left at the start/finish pavilion for delivery to the mile 5 aid station; each drop bag must include the athlete name, race distance, and bib number. Participants who begin loops late in the day must carry a headlamp or other personal light. The optional hill climb for “Be Knighted” is a marked 0.15 mile climb each way behind Squire's Castle; participants receive a token at the top to carry to the finish.
