This is the classic Morgul-Bismark ride near Boulder, Colorado, and featured in the movie American Flyers. After an initial warm-up leaving Boulder, we head up a gentle grade towards the city of Superior. Leaving Superior, we take the first steeper hill called "The Hump". Next up is "The Wall". Turning right onto the rolling HW 128 there's one more big climb before we head back towards Boulder.
