The 50K start time is 7:40 a.m.  Cut-off time for the first loop will be enforced at 11:40 a.m., or four hours from the start time. During the second loop of the 50K distance, runners must pass the last aid station (approx. five miles from the finish) prior to 3 p.m., or seven and a half hours from the start time. Final cut-off time is nine hours. All cut-off times will be strictly enforced. Runners must be checked OUT of the aid station BEFORE the cut-off time.

There will be three aid stations, one at the start/finish and the other two approximately five miles apart on the course. Each aid station will be supplied with water, electrolyte drinks, gels, snacks, first aid and enthusiastic volunteers! Restrooms will be available at the start/finish.
