The Urban Assault Ride™ is a truly unique cycling event and quickly becoming one of the biggest in country! Here's how it works: You and your teammate will set out on a quest around Berkeley for 'checkpoints' on your favorite two-wheeled steeds. At each checkpoint, you'll drop your bikes and complete a funky/adventurous obstacle course guided by EBBC volunteers, then remount your bikes and hit the streets for more. The goal is to complete all the checkpoints in the shortest amount of time. You choose your own route and checkpoint order. This means that the most clever are often the victors. Of course, it may also help if you can pull a mean big-wheel powerslide and fly across an inflatable slip-n-slide. Benefiting: East Bay Bicycle Coalition and Bicycle Trails Council of the East Bay.
