An aid station is located at the changeover between the two trails and is stocked with electrolyte drink, water, and hot quesadillas. Pacers are permitted only for the 100 Mile and 100K distances under specified rules; pacers must check in and pick up a pacer bib. No pacers, including cyclists, are allowed for other distances.
