WinterRock Trail Race Independence, KS   Jan 3, 2026

The WinterRock Trail Race is a somewhat Fat-Ass Style Event to kick-off the new year! Very LIMITED aid (unmanned, water only), no chip timing, post-race food will be available. The course is on the Elk River Hiking Trail, an accurately measured forest trail winding through unique limestone bluffs, rock formations & picturesque vistas.

Technical, mostly single-track, out & back, very rocky, no long hills. 3 Aid Stations in the 25K and 1 (turnaround) in the 12K. Aid stations are approximately 3.5-4 miles apart, are all unmanned, with only water available. No cups will be available, so you MUST carry a handheld bottle with you on the course. If you need fuel (calories) of any type, YOU are responsible to pack it with you, as there will be none available on the course. Shirts and Medallions will now be given at WinterRock!!!

The history behind these races is immense with FlatRock being the first and oldest trail ultra in Kansas!! This is a must run trail series. Come see this unique aspect of Kansas like you have never experienced it before!
