But we do have one new ride debuting. (If you are organizing one not on the list, email 'glen' at this website, and I will try to add it.)

Urban Assault Race

This race - a combination adventure outing, scavenger hunt, and bike ride - returned to Colorado with rides in Ft Collins and Denver last year. Two-person teams got to chart their own route to visit 5 or 6 checkpoints, where they took part in such activities as riding Big Wheels thru an obstacle course. Riders used their thinking cap (or a friend sitting at a computer, whom they called on cell phone) to decipher the clues to reach a handful of landmark checkpoints. For 2011, lOcal rides are in Fort Collins (July 17) and Denver (July 24). Check out for details.
