JEFFERSON, S.D. (Aug. 18) – IMCA Modified driver Jay Noteboom stole the show Saturday at Park Jefferson Speedway.
Noteboom notched career win number 74 at Park Jefferson to pass Late Model Hall of Fame driver Joe Kosiski as the speedway’s all-time feature winner.
With tears in his eyes, Noteboom accepted the checkers and trophy from flagman Nate Peterson.
It was not an easy battle in the Artworks Graphics IMCA Modified special, as Chris Abelson was first to move to the lead on the multi-lane oval. Toward the late stages, Abelson drifted high off the track and gave up the lead.
Noteboom saw his chance and pounced, then held off the challenges of Bob Moore to take the historic win. Abelson was third.
Ryan Voss took the IMCA RaceSaver Sprint Car win and Colin Smith the unofficial 2018 track championship.
JEFFERSON, S.D. (Aug. 10) – All of eight tenths of a second made the difference in Monday night’s Iron Cup main event for IMCA Modifieds at Park Jefferson Speedway. Jacob Hobscheidt led the entire 35-lap feature but had to hold off a hard running Shane DeMey in the closing laps to pick up the $5,000 win by a fraction of a second. “I raced there a handful of times but never had any luck,” Hobscheidt said after matching his career-best payday. “The last four or five laps I was running out of fuel and doing whatever I could to keep the thing running.” Hobscheidt got the early jump on the field over fellow front row starter Bob Moore and cruised early. Action was fierce back in the back of the pack as DeMey working around the low side in coming from 10th starting. DeMey finally moved around Moore and rookie Cody Thompson to secure the second spot but simply ran out of laps at the finish as Hobscheidt, already Fast Shafts All-Star Invitational qualifying eligible, took [Read More]
By Ben Deatherage JEFFERSON, S.D. (May 19, 2026) — One of the most anticipated special events of the summer at Park Jefferson Speedway returns on Sunday, June 14, as the 5th Annual Dave Riley Memorial Race honors the longtime Siouxland racer with a loaded night of Speedway Motors IMCA Weekly Racing action. The event celebrates the legacy of Dave Riley, who spent most of his racing career competing in the IMCA Hobby Stock division before racing an IMCA Northern SportMod during his final season in 2017. Over the past four years, the memorial has grown into one of the marquee events at the high-banked South Dakota oval. “This race has been a huge success the last four years commemorating dad,” said Dave’s son, Chance Riley. “It brings the community together and everyone has a great night of celebration in honor of Dave.” A massive purse awaits competitors across all five IMCA divisions. Sunoco IMCA Hobby Stocks headline the event with a $3,056 winner’s share, while Karl Kustoms IMCA Modifieds race for $2,056 to win. Sunoco IMCA [Read More]
By Chance Riley JEFFERSON, S.D. (Apr. 24, 2026) — Friday night racing at Park Jefferson Speedway saw the Sunoco IMCA Stock Cars steal the show for the third straight week, and this time it was Sioux City, Iowa’s Greg Peck who made the winning move when it mattered most. Mike Vondrak paced much of the 18-lap main event, just as he had the week before, but was under constant pressure from a pack of drivers racing two- and three-wide behind him. Peck, who started sixth, methodically worked his way forward before making a late-race pass to score his first win of 2026 in the EQ Cylinder Heads Northern Region. Vondrak settled for second, followed by Lowell Roeber in third. Travis Baker finished fourth, and Todd Gereau rounded out the top five. In the Karl Kustoms IMCA Modifieds, Sioux City’s Greg Taylor completed a clean sweep on the night, picking up his first win of the season in the Razor Chassis North Central Region. Jimmy Cole ran second, followed by R.J. Merchant, Shane DeMey, and Ricky Stephan. [Read More]
