Beautiful ride along the foothills of southern Colorado. With 319m of continuous elevation gain, it is not a slouch ! Ride is called after most famous "attraction" in the area - the most secure prison in America, aka as ’Alcatraz of the Rockies’, home to most notorious criminals, terrorists and spies in America. The ride goes right by ADX (on the left) - we put a point of interest to mark the spot around km 2.5. Picking up hitchhikers is not advised :)
