We will again have 14 aid stations for the 100 Mile race, plus two unmanned water stations. I’ve included the GPS coordinates for the locations as well as instructions on how to get to each of the aid stations where crew access is allowed. Crew access is permitted for 5, 7, 8, 9, 10, 11, 12, and 14. No crew access is permitted at 1, 2, 3, 4, 6, and 13.

All aid stations will have toilet facilities of some kind. 4, 6, and 13 will only have "Porta-Loos", which are basically 5-gallon buckets with a seat. The others will have standard event toilets. 

Drop bags will be available at all Aid Stations except Salt Flats (Aid 1). DO NOT bring drop bags to the pre-race mtg. We'll have labeled tarps for drop bags at the start, but please make sure they're placed in their appropriate Aid Station bins no later than 1/2 hr before the start. The salt desert is a unique environment, and wind is generally a constant. As a result, if the winds are high, the aid stations may not have shade canopies as you’ll find in many of the other 100’s. Plan accordingly with your aid station bags and/or crew support.
