Urban Assault Race

How fun is this? Check out the Urban Assault Race. You've got two chances to get your act together and build a two-person team, with the Urban Assault Race hitting Denver on July 30 and Boulder on Aug. 27. It's like a bike race/obstacle course/scavenger hunt/adventure race. About 25 miles. There's a shorter family race too. It's a little pricey but you could also win bikes.
