In just eight days, two new champions of the USRA Iron Man Challenge will emerge. With the final four events of the 2011 campaign between now and then, the racing action will be boiling hot as the USRA Karl Chevrolet Stock Car and USRA Karl Performance Parts B-Mod drivers battle it out for this year’s titles.

The Iron Man Challenge featuring USRA Karl Chevrolet Stock Cars and USRA Karl Performance Parts B-Mods will be a part of the program with the USMTS Modifieds on Wednesday, Aug. 31, at the Fairmont Raceway.
