Get ready to tackle 27 miles and nearly 6,700 feet of elevation gain on the highest paved road in North America, climbing from Idaho Springs all the way to Mt. Blue Sky's 14,130-foot summit! This legendary event, running since 1962, honors Bob Cook, a US Olympic athlete and record holder who passed away from brain cancer at just 23 years old. You'll have the road completely closed off for safety and an amazing experience as you're part of this historic memorial ride.
