The 7-mile Waldo Canyon Trail, although primarily a hiking trail, does invite gonzo-minded mountain bikers to strut their stuff.  What makes this trail particularly appealing to tough riders is its steep climbs out of creek beds and its fast and rocky descent--added to this is the variety of terrain Waldo Canyon delivers.  Views from its highest point include Pike's Peak, Colorado Springs, and NORAD.
