About the race

The Shippey Endurance Runs is a multi-distance trail event held at Beaumont Scout Reservation near High Ridge, MO on January 16–17, 2027. The event is organized by PR Racing and uses the Scout ranch trail system, which is normally closed to the public during the year.

Course terrain includes steep climbs, ridgeline running, long and short steep descents, creek bottoms, pine floor, and jeep roads. The route is approximately 75% single or double track and 25% jeep roads. The course direction alternates by year, running clockwise on odd years and counterclockwise on even years. There are two indoor aid stations that runners will visit multiple times.
