Course Description:

The Cog Run is a challenging 8.4 mile out and back course on Routt County Road #76. This race has approximately 3 miles of steep uphill and 3 miles of steep downhill slope with the turnaround point at the top of the Hayden Cog. Race offers spectacular views of the Yampa Valley.

The 5k run is out and back following the same direction as the longer race. You will cross the bridge spanning the river and turn around a half mile or so after the road turns to dirt.

One water station provided for on the 8.4 mile course ONLY, minimal aid station for the 5k. In an effort to go cupless, we ask that you bring your own device for carrying water.

Pets: Not advisable for the Hayden Cog Run, considered for the 5k
