The Iron Man Challenge will kick off the 2018 campaign at the Humboldt Speedway in Humboldt, Kan., during the King of America VIII Modified Nationals presented by Summit Racing Equipment.

Out-Pace USRA B-Mods will join the fire-breathing Modified of the USMTS for three days straight on Thursday, Friday and Saturday, March 15-17.

“Everything will pretty much remain the same for the Iron Man Challenge in 2018,” said USRA President Todd Staley. “Payouts with the bonus bucks will be intact for all races, and there will be several shows in 2018 that will not be part of the USMTS campaign.”

Twenty-one nights are currently on the Iron Man Challenge schedule, and this will be the only stand-alone event for the B-Mods as the remaining slate of races will feature both the B-Mods and Holley USRA Stocks presented by Medieval Chassis.

B-Mods will count their best 16 starts and must race in at least 14 of them to be eligible points funds. Stock Cars have 18 races on tap and we will take your best 14 and must race in 12 of them to get points funds. Please keep in mind that there are likely to be some more races added as well as some rain-outs.

All Iron Man Challenge shows also award Summit USRA Weekly Racing Series national points in both divisions.

The next event on the calendar is a three-day, three-track swing of Frost Busters, April 5-7. Action begins Thursday at the 81 Speedway in Wichita, Kan., and then moves to the Lakeside Speedway in Kansas City, Kan., on Friday before wrapping up the tripleheader on Saturday at the I-35 Speedway in Winston, Mo.
