Photos: New Belgium's Urban Assault Ride in Denver

The Urban Assault Ride, the nation's biggest bicycle obstacle event series, took place on the streets of Denver on Sunday, July 21, with competitors racing Big Wheels and BMX bikes along the route. Teams of two set out on a city-wide quest for checkpoints, dropping their bikes and completing a funky and adventurous obstacle course at each stop.
