The September issue of Bicycling magazine featured an article called "The Best Bike Ride In Every State". Personally, it would be hard for me to pick the best ride in Colorado, from all the great rides I've done. Perhaps Durango to Ouray, 70 miles on the "Million Dollar Highway" with 7000+ feet of climbing?
Olympic medalist and seven-time Tour de France rider Ron Kiefel has ridden Mt. Evans—the highest paved road in the United States, at 14,265 feet—a few times in his life. Make that 20. “Evans isn’t the steepest or craziest mountain I’ve ever done,” he says of the 6,575-foot, 18.4-mile ascent. “But it’s a complete classic. There aren’t many places you can climb for four hours straight.” From Idaho Springs, the highway passes shallow Echo Lake and breaks out of treeline into a rocky, lunar landscape. Up there, a 6 percent grade feels like 10. And the views? South, there’s 14,110-foot Pikes Peak. North, there’s 14,259-foot Longs Peak. West, there’s the endless Rockies. And on a clear day, looking east past Denver, you can actually see the curvature of the earth. “Not many people can say they’ve been up here with a bike,” Kiefel says. “I look at it as a journey and an adventure.”
I can say that I've been up there with a bike. And it was awesome!
