Breathtaking views of the Flatirons mark this iconic Boulder climb, where the pros battled it out for a stage win in the 2013 USA Pro Cycling Challenge. For the hardcore, the ’Super Flag’ version of this ride goes past the amphitheater up to the set of mailboxes at the top, at around 8,000 feet. It’s ’only’ another two miles, but the majority of it averages a more-than 10 percent gradient.
