The first video from Flotrack – CU Long Run at Gold Hill. Thought this would be appropriate as the USATF XC Championships are in Boulder today.
This run is typically an out and back and if I remember correctly it’s 17.0 or 17.5 miles. There is a 20 mile loop that takes you through Ward, then south on the Peak to Peak highway, then back on the road to Gold Hill. I did it a couple of times. Definitely the craziest 20 milers of my life due to topography and elevation.
