Take part in Colorado's booming cycling culture—at least for the day. During this environmentally friendly and stress-reducing ride to and from work, thousands of fellow residents will ditch their cars and rush-hour traffic to promote the benefits of commuting on two wheels. Wed, times vary.

What’s better than getting exercise, saving gas, and avoiding a sea of red taillights on your morning commute? Almost nothing—except finishing off the day with free beer, food, entertainment, and schwag. After work, join more than 3,000 fellow two-wheelers for this annual Bike to Work Day culmination party.
