This is STL’s Original 100-mile trail ultra!!

Nestled quietly in the rolling wooded hills just outside of Greater St. Louis lies the wonders of the Beaumont Scout Reservation. Here we invite you to partake in a first-hand experience of these “rolling” hills, where, under normal circumstances the general public is not allowed to run the tough and beautiful trail systems within.

The Shippey Endurance Runs, rightly named from the trail color system used by the Scouts, after Merle Shippey a well-respected cog in the scouting community. The Shippey takes you through all aspects of this magnificent wonder by creating an extremely runner, crew and aide friendly race.

No need to chase runners over miles of back roads. Camp indoors 100 yds from the Start-Finish line and the ease of seeing your runner or your crew every 3-5.3 miles The Shippey is minutes from amenities, allowing runners and their crews the ease of re-supply and convenience nearby!!

Come prepared for cold temps but also know that it could be 70 degrees. Weather in St. Louis can flip on a dime!
So, if you want to run on an amazing trail system that will only be open to the public during this event….well, come run with us at The Shippey Endurance Runs!

P.S. the Boy Scout’s didn’t believe in switchbacks when they built these trails! You have been properly warned!!
