Aid Stations, Pacers, Crew & Cut Offs

We will again have 14 manned 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, 11, 12, and 14. No crew access is permitted at 1, 2, 3, 4, 6, 10 and 13.

East Silver Island Loop Road is now OFF LIMITS to ALL RUNNER CREW vehicles. This is often referred to as the "Front Side" of the course.  This change is due to ever changing road conditions. ONLY HAM, SAR, AS Volunteers & STAFF are allowed to access this road during the race.

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 the following Aid Stations: 3, 5, 6, 7, 8, 9, 10, 11, 12, 13 &14. 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 by 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.

Pacers:

Pacers are welcome to join you starting at AID STATION 5/7 & continue with you for the remainder of the race. Please only plan on swapping out pacers at aid stations which have crew access (5/7, 8, 9, 11, 12 & 14) as dropping off a pacer is not a reason to go to a “closed station” & we do not have time to provide transportation to aid stations.
