About

All runs will take place on the Switchgrass Mountain Bike Trail at Wilson State Park. The 100 has the most elevation gain and loss of any 100-miler in Kansas! If you're looking for a challenging course in the "flatlands" you've found it. The trail is easy-to-follow, rugged, single-track with very few trees/wooded areas. Beautiful views of Wilson State Park and Wilson Lake are abundant.
