This is a long and very challenging run, with plenty of hiking mixed in. Getting in to the trail requires a long steep ascent with lots of loose rock. See if you can keep a nice incline on your treadmill! On the shadier north side of the mountain we encounter long stretches of mud and snow. But enjoy this Colorado Spring run and the amazing beauty within Red Rocks Park, famous for the Red Rocks Amphitheater located within the park, one of the world’s best places to catch a live concert. The total distance traveled is about 4.25 miles.
