ThunderBunny 50K

All Day

The Thunderbunny 50K comes to Strouds Run State Park and will show off some of the best trails in the region and give participants a great experience, whether you are a first timer or a trail veteran. The course starts and ends on the famous 3 mile Thunderbunny Trail, and in between runners will complete a loop around Dow Lake and run up and over a ridge to overlook the city of Athens!

With the course boasting 95% singletrack trail, this will quickly turn into a favorite for pure trail runners. While showcasing some of the great Appalachian Foothills that Athens is known for, this is also a very runnable course so it is a perfect option for your first ultramarathon or first trail race! Along with the 50K, there will be two shorter course options of 25K and 12K to choose from.

Permits:  This event is held in accordance with special use permits from the Ohio Department of Natural Resources for Strouds Run State Park.  Please be considerate of the land and other users to ensure the future of the Thunderbunny.
