Race Details
The courses are characterized by steep ascents and long, technical descents. Aid stations are situated less than 10 km apart, providing water, electrolyte drinks, and various snacks. This is a cup-less event, meaning runners must carry their own collapsible cup or bottle for refills.
A unique requirement of the race is the "Skeleton Key" provided to each participant before the start. Runners must carry this key at all times and may be asked to show it during the event. The race kit includes a bib, a race shirt, a sticker, and a finisher medal for those who complete the course within the 12.5-hour time limit.
