Independence, KS

The history behind these races is immense with FlatRock being the first and oldest trail ultra in Kansas!! Epic races such as the 2017 flood year have become the stuff of legend and lore! This is a must run trail. Come see this unique aspect of Kansas like you have never experienced it!

Beginning in 2022, the FlatRock Fall races will feature distances of 101 mile, 101K, 50K, 25K, and 12K. There will not be a spring race or a triple crown series.

The course consists of a 50K loop which is run twice for the 101K and will be run three times plus an additional out and back along the same course to reach the 101 mile distance. There will be a 36 hour cut-off for all race distances. For the 101 mile, you must begin the third loop by 24 hours and the partial loop prior to 33 hours. Drop downs will be allowed to receive a medal for the longest distance completed subject to availability. The 101 mile finishers will receive an 8 inch buckle!!! 

A technical, mostly single-track, out and back along the Elk River Hiking Trail. Accurately measured forest trail winding through unique limestone bluffs, rock formations & picturesque vistas.
