CONCORD, N.C. – The most grueling Hell Tour schedule in history just got even hotter.

Five races have been added to the DIRTcar Summer Nationals late model schedule, making a new total of 35 race dates across nine states from June 15 to Aug. 21.

Four races have also been added to the Summit Modified Nationals calendar in their 11th season of competition for a total of 34 dates – the most in tour history.

The new dates begin with a first-ever visit to the Knox County (Ill.) Fair Raceway for both the late models and UMP Modifieds on Tuesday, July 6. The following night, July 7, both tours return to the Belle-Clair Speedway in Belleville, Ill., for the first time since 2016.

Week No. 6 has also been filled-in with a trio of races, starting with a return to the Randolph County Raceway in Moberly, Mo., on Wednesday, July 21 for both tours’ second-ever appearances at the high-banked half-mile.

A visit to Springfield Raceway the following night will set the stage for a late model-only show on Friday, July 23, a $10,000-to-win affair at Lake Ozark Speedway in Eldon, Mo. – marking the third visit in tour history.

The two tours then meet back up at Clarksville Speedway Saturday night before heading out to Kentucky on Sunday, July 25 for a debut at the three-tenths-mile Richmond Raceway in Kentucky.

The lone stop in the Bluegrass State marks nine different states the tours will visit this year.

The grind kicks off for both tours at Indiana’s Brownstown Speedway on Tuesday, June 15.
