GRAIN VALLEY, Mo. -- Officials at the United States Racing Association announced today that the Valley Speedway in Grain Valley, Mo., will host the Industrial Material Surplus Iron Man Challenge for USRA B-Mods on Saturday, June 23, and again on Thursday, Aug. 9.

Both events will pay $500 to win and $75 to start the main event.

The USRA B-Mods will race in conjunction with the USMTS Modifieds at both events. The June 23 show will be a USMTS National Championship Series event while the Aug. 9 stint will be part of the Hunt for the USMTS Casey’s Cup.

The third season for the Industrial Material Surplus Iron Man Challenge boasts 29 dates at 14 popular dirt ovals in 6 states. On the calendar are 27 shows for USRA B-Mods and 15 for the full-fendered USRA Stock Cars. Both classes will race together on 13 nights, USRA B-Mods will have 14 solo nights and Stock Cars will have 2 nights to themselves.

Last season 367 tough-as-nails drivers took part in the Iron Man Challenge, including 237 different USRA B-Mod drivers and 130 USRA Stock Car competitors.

Points will be determined by the best 12 finishes for USRA B-Mods and best 10 finishes for USRA Stock Cars. To be eligible for points funds, drivers must possess a valid USRA license, utilize the American Racer KK704 racing tire on all four wheels and compete in at least half of the events for their division. Licensed USRA drivers in both classes will also earn national points in the American Racer USRA Weekly Racing Series.
