For those still trying to catch their breath after last week’s epic finishes at the Great American Stock Car Shootout, officials have announced that race fans will be allowed to bring their defibrillators into the grandstands this Wednesday when the Iron Man Challenge delivers another night of heart-stopping action in Oskaloosa.

‘Simply incredible’ was a commonly heard phrase last Tuesday following the main events for the USRA Karl Chevrolet Stock Cars and USRA Karl Performance Parts B-Mods at the Southern Iowa Speedway.

The B-Mod feature saw a green-white-checkered finish with Cayden Carter powering to his fourth win of the season at the Mahaska County Monster while the Stock Car finale produced multiple lead changes and a swarm of full-fendered machines swapping positions every lap before Kevin Donlan finally crossed beneath the checkered flags first in a jaw-dropping finish.

WARNING: The event will feature the Iron Man Challenge Stock Cars and B-Mods racing in conjunction with the high-powered USMTS Modifieds, so race officials recommend that those with severe medical problems and women who are pregnant or nursing get really good seats!

Fans will also get plenty of excitement before and after the races as Wednesday’s show will be during the Southern Iowa Fair presented by KBOE Radio with dozens of activities for families and people of all ages, including games, shows and lots of great food.

Casey’s General Stores will have discount coupons good for $2 off adult admission at all three Casey’s locations in Oskaloosa on race day. To find the location nearest you, visit www.caseys.com.
