Review: I love this run. It has a bit of everything. The main loop is just over 12 miles long through gorgeous mountain ranch lands, deep lush ravines, and across the sides of steep canyons. Much of it is like running on top of the world, with very few people and endless views. Start on Hwy 6 in Clear Creek Canyon to add 4.5 steep and spicy miles to an already extraordinary trail. This is perhaps the most unique and enjoyable trail runs within Jefferson County's amazing collection of mountain park jewels.
