Course & Aid Stations

1 Loop =  ~20mi with ~2,800ft of elevation gain
100mi = 5 Loops & ~14,000ft of gain with a 33 hour time limit
100k = 3 Loops & ~8,400ft of gain with a 23 hour time limit

There are 4 aid stations that you pass through a total of 5 times per loop. The furthest distance between aid stations is approximately 6.3mi and the shortest stretch is approximately 2.1mi. The first hard cutoff is for the start of a runner’s final loop and each on-course aid station will have a subsequent cutoff for that final loop.

All aid stations will be manned by incredibly helpful volunteers and fully stocked with a minimum of water, Tailwind (100cal/12oz ratio), soda, salty & sweet snacks, fresh fruit, hot and cold food and basic first aid. Trust us when we say, we are going to take GOOD care of runners but if you do have strict dietary requirements or specific medical conditions, we advise packing needed items in drop bags or carrying them with you.

Drop bag service is provided at ALL 4 aid stations.
Crews and pacers are ONLY allowed at the start/finish aid station.

We plan to have an exact course map and elevation profile along with a detailed aid station chart up on the site in the coming months but we want to wait until we’ve got the last few small bits of the route ironed out before posting anything definitive publicly.

In the meantime, to help folks who are unfamiliar with the area visualize the layout of the trails and the park, we’re including the official Mines of Spain trail map below with the S/F location noted in the top left. The race course will utilize all but a tiny portion of the colored trails shown in the map and included in the legend.
