We’re used to the Col Collective treating us to videos of some of the most stunning climbs to ride from across the world.

Now, it’s time for something different – but, insists Mike Cotty, that doesn’t mean it’s any easier.

The Col Collective teamed up with former US national champion Timmy Duggan and Craig Lewis, a former team-mate of Mark Cavendish at HTC-HighRoad to explore the best Boulder, Colorado, has to offer.

The Boulder Big Ride covers 61 miles of high-altitude riding, dirt roads and challenges such as the Super Flagstaff Road and Gross Dam.
