Hell Creek Half & 50K Sylvan Grove, KS   Aug 29, 2026

All runs will take place on the Switchgrass Mountain Bike Trail at Wilson State Park. The trail is easy-to-follow, rugged (yet 100% runnable), single-track with very few trees/wooded areas. Beautiful views of Wilson State Park and Wilson Lake are abundant. This is a BEAUTIFUL course and the only EPIC rated mountain bike trail between the Rockies and the Ozarks.

The 50K will has about 3000 ft of elevation gain/loss, while the ½ marathon will has around 1300 ft gain/loss.

The ½ marathon will be one 13(ish) mile loop with an initial 1/3 mile on pavement. The 50k will consist of a 19-mile loop, followed by another loop on the ½ marathon course. The 50k will be closer to 32 miles.

The course will be heavily marked with ribbons, flags, and wrong-way signs. This is an extremely easy course to follow.
