Event Overview
WinterRock is a trail running event held on January 2, 2027, in Independence, Kansas. The race serves as a kickoff event for the new year and is organized by the FlatRock Race Series. Participants navigate a technical, mostly single-track course along the Elk River Hiking Trail. The terrain features unique limestone bluffs, rock formations, forest paths, and scenic vistas.
The event follows a Fat-Ass style format with limited, unmanned support on the course. While the race is self-sufficient in nature, finishers receive medallions, and post-race food such as Frito Chili Pie is provided at the staging area. The start and finish lines are located at the Outlet Channel Shelter on the north side of the Elk City Lake dam.
