Course and logistics
Courses are marked with ribbon approximately every 200 yards and color coded by distance. Polka-dot flagging indicates turns; blue ribbons mark the wrong way. Aid stations are fully stocked every 5 - 9 miles with fresh fruit, salty snacks, candy, water, and Skratch electrolyte drink. Runners are recommended to carry at least 20 oz of water between aid stations.
The event is cupless to reduce waste; participants should bring their own fluid container. A limited number of Hydrapak SpeedCups are available for sale at check-in. Timing uses bib tags by MyLaps and results are published periodically during the event. Marathon and 50K have cut-offs at the Bear Gulch aid station (11 miles); all events have an overall time limit of 8.5 hours. Overall and age group placing are based on Clock Time.
