Todd Staley won the Holley USRA Stock Car feature.

The Iron Man Challenge invaded the Park Jefferson Speedway on Saturday for the Dave Mulder Memorial which carried a padded purse for the Holley USRA Stock Cars presented by Medieval Chassis.

Making his first Iron Man start of the 2018 campaign, Zach Olivier beat polesitter Todd Staley to the first turn and took charge of the 18-lap main event.

Staley, defending series champ Derek Green and current points leader Dillon Anderson followed closely throughout the contest but contact with another car on lap 6 sent Green to the pits with a flat tire while Brett Heeter, who started 19th, entered the top five for the restart.

Oliver continued to lead through the first dozen laps until Staley and Heeter made a bid for the lead as they raced toward the flagstand to complete lap 13.

Staley grabbed the lead in turn 2 but Oliver and Heeter kept the pressure on. Unshaken, Staley was able to hang on for a $1,150 payday and his third Iron Man Challenge win of the season.

Oliver finished second while Green bounced back to overtake Heeter for the third spot in the closing laps. Anderson rounded out the top five with Dylan Fitzpatrick, Roger Verdoorn, Glenn Wynia, Brad Jones and Paul Wenzlaff were sixth through tenth, respectively.

In the main event for the Out-Pace USRA B-Mods presented by Pace Performance, Jeff Brunssen led the first lap from the outside of the front row but polesitter Tyler Johnson reclaimed the point one lap later.

Despite multiple cautions that kept the field within striking distance during much of the contest, Johnson never relinquished the top spot and paced the final 17 laps to a $500 victory.

Tyler Johnson won the Out-Pace USRA B-Mod feature.

Jake Sachau was second at the checkered flag, Cody Thompson claimed third, Tracy Johnson raced from 18th on the grid to finish fourth and Reese Coffee came from 19th to fifth.

Connor Vande Weerd, John Klynsma, Brunssen, Jared Timmerman and Cole Christensen completed the top ten.

Working Labor Day Weekend: Four big nights or Iron Man insanity are on tap for Labor Day Weekend, beginning Thursday, Aug. 30, with the make-up event from Friday’s rain-out at the Rapid Speedway in Rock Rapids, Iowa.
