Chisholm cashes in on Thornton’s heartbreak at Mason City

The Summit USMTS National Championship presented by RacinDirt kicked off the three-day 10th Annual USMTS North Iowa Nationals presented by Christie Door Store on Thursday at the Pritchard Family Auto Stores Mason City Motor Speedway.

In a prelude to the 25th Anniversary USMTS Silver Jubilee here Aug. 16-19, Dylan Thornton looked to be on his way to his career-first USMTS triumph after leading the first 30 laps of the main event at North Iowa’s Action Track.

A flat tire with five laps to go doomed the young gun’s dreams while eighth-starting Jim Chisholm of Osage, Iowa, picked up the pieces and sped to his fifth USMTS win of his short career.

After Thornton’s blow out, 2021 USMTS National Champion Dereck Ramirez assumed the lead but Chisholm was far too strong and pulled away over to a margin of victory of more than two seconds during the final four circuits.

Behind Ramirez, four-time USMTS titlist Jason Hughes grabbed the third-place paycheck while Alex Williamson and Tim Ward completed the top five.

Grant Junghans USMTS Rookie of the Year points leader Tom Berry Jr.. was sixth, followed by Al Hejna, Gary Christian, Jake O'Neil and 18th-starting Cayden Carter.

The FK Rod Ends Hard Charger Award went to Aaron Benson who started 22nd and finished 12th.

One down, two to go: Another 48 hours of action-packed dirt-flavored adrenaline remain on Friday and Saturday. The feature win on Friday will be worth $5,000 and Saturday’s USMTS North Iowa Nationals champion will take home a cool $10,000 for his or her efforts.

The next two shows will feature the mud-slinging WINS Sprint Car Series racing for $700 to win Friday and $1,200 to win Saturday. On top of that, fans will witness school bus races on both nights.

The pit gates opens at 4 p.m., grandstands open at 5 each day. Following the drivers meeting at 6:15, hot laps and qualifying begins at 6:30 with racing to follow around 7:10. All times are Central Standard Time. Youth ages 17 and under must have signed Minor Release to enter the pits.

The Mason City Motor Speedway is a 1/3-mile clay oval located 5.1 miles east of I-35 at exit 194 on SR 122 (at the North Iowa Fairgrounds). For more information, call (515) 832-6000 or check out MasonCityMotorSpeedway.com. You can also follow MCMS on Facebook, Instagram and Twitter.
