We are VERY excited to be returning to the Chicago area for the 2012 Chicago Merrell Down & Dirty National Mud and Obstacle Series presented by Subaru. We are getting incredibly close to selling out our 8:00 am 10K race, so if you have yet to sign up, now is the time! If you are looking to sign up for one of our 5K races, those are estimated to sell out as well. Sign up NOW!
See you in the mud!
