Crew Access

Athlete crew will have access to all aid stations on the course. Athletes are allowed access to their crew at designated aid stations. A pacer is still allowed after dark starting at the nearest aid station.

*All aid stations will have access to a fire for your warmth and comfort. Don’t stay too long or you’ll never leave. Each aid station will include water and a hydration product, limited sandwiches, and all of your ultra candy affairs. The start/finish aid station will have some extra fare including warm sandwiches with an extra special touch. Warm soup will be waiting for each runner at the start/finish area no matter if you run one mile or finish the race.
