Cliff Runner

The Cliff Runner 10K is an extreme trail running event held in Sherwood, Wisconsin, within High Cliff State Park. Covering a challenging 10-kilometer course, the race features mostly single-track trails with natural obstacles such as rocks, roots, boulders, and hills, accumulating over 500 feet of elevation gain. This race offers a true trail running experience through some of the park's most demanding sections.

Participants receive a Cliff Runner T-shirt and finisher's medal, with a portion of proceeds benefiting the Purdy Nature Preserve at the Apple Creek YMCA. Runners must have a day pass for the state park to participate. The event is praised for its well-organized, motivating atmosphere. Visit the organization's website for the most recent information.
