Relay Information

This 6-hour trail relay is a team event where teams of 2-3 runners tackle a 4-mile loop to maximize total laps. The team with the highest number of laps, followed by the fastest total time, wins.

No new laps may begin after 5 hours and 35 minutes.

Aid Station Info

There will be one aid station at the S/F and you may set up your own canopies or tents in the designated drop bag area ONLY. The neutral aid station will be stocked with the usual water, Hyperlyte Liquid Performance drink mix, coke, ginger ale, pickle juice, gels, and an assortment of sweet and salty snacks. This is a cupless race so please bring your own bottle, bladder, or cup.

Cutoffs

Only fully completed laps count toward your race distance and the final lap must be completed BEFORE the race finish per the above schedule, based on the event in which you are registered. Therefore, it is at your discretion if you begin a 4 mile loop that you know you may not be able to complete before your race ends. There will be an absolute cutoff 25 minutes prior to the end of each race (9:35 am for the 3 hour, 12:35 pm for the 6 hour), after which no runner will be allowed to begin another loop.
