Dark Divide Night Run
As a part of the Great Divide Ultras running festival, we are introducing the Dark Divide Night Run! This night run begins at 8:00PM as the sun is setting on Saturday. This incredible run offers runners an opportunity to share the trail with the 100mile/100k runners and to practice running through the night.
