The Merrell Down & Dirty National Mud and Obstacle Series presented by Subaru will make a second visit to the Windy City on May 20th, 2012!

This year Chicago's Pop/RB Chameleon, Troy D., will be opening the event with the National Anthem.

Chicago pop/rb singer Troy D. falls in luv with a new kind of sound. You might remember him as the 2010 Voice of ESPN, the 2010 Road to Fame Winner, the Chicago White Sox's National Anthem,and even his stunning performance in Hollywood & Las Vegas.
