Course and logistics

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.
