MERRILL, Mich. Officials with the Great Lakes Lightning Sprints Presented by MacAllister CAT Rentals have released the upcoming schedule of events.

Moving into the sixth season as a traveling Winged 1,000CC Micro Sprint Series, the schedule includes familiar Michigan facilities plus another trip to Ohios Millstream Speedway and a brand new event that displays the Great Lakes Lightning Sprints as the headlining division.

The season begins on May 10 at Silver Bullet Speedway. Located in the thumb of Michigans lower peninsula, Silver Bullet will host all three of the Great Lakes Sprints divisions in 2025. Last seasons opener was washed away at Silver Bullet, but in the return visit, Jacob Sabaj came from fourth to grab the win. In the final visit of 2024, Justin Ward started on the pole and held off Sabaj to close out the season as a feature winner. This season, GLLS will unload at Silver Bullet twice, both dates in the opening month, May 31 being the second and final visit for GLLS.

Mt. Pleasant Speedway returns to the schedule four times this year. Brendon Cascadden came from the pole to grab the spring win at Mt. Pleasant in 2024 and started six for his second win in June. Sabaj took the honors in August. Fans can catch GLLS this season on May 16, June 6, July 4 and Aug. 15.

Under new management this year, Tri City Motor Speedway in Auburn, Mich. is back on the GLLS calendar once again. Sabaj held off Ward during the first July visit in 2024, but Ward came from ninth to win the second July event last season. Sabaj returned as a winner over Ward again in August. In 2025, GLLS fans can catch the action on May 23 and July 11.

Crystal Motor Speedway appears on the 2025 schedule alongside Tri City Motor Speedway for one of two doubleheader weekends for GLLS this season. May 24, June 14, Aug. 2 and Aug. 30 are all dates reserved for GLLS at Crystal this season. Sabaj was a spring winner ahead of Ward, Eli Wilhelmus won last June, Lindsey Erickson handled business in July, and Sabaj returned to Victory Lane in September.

Merritt Speedway, often hailed as the birthplace of Lightning Sprint racing in Michigan, is back on the 2025 schedule for a pair of dates. First, June 28 and then again on July 19. Sabaj had an impressive performance in last seasons first Merritt race, charging from 13th on the grid to snooker Ward for a massive win. Ward got his victory, however, during the return visit in July.

On July 17 the Great Lakes Lightning Sprints Presented by MacAllister CAT Rental takes center stage during the Ionia Free Fair at the Ionia County Fairgrounds. GLLS will headline the event alongside other thrilling circle track divisions still to be announced.

Millstream Speedway requested a spot on the 2025 GLLS schedule once again. Last year, Lightning Sprints graced the schedule in August at Millstream Speedway with Sabaj winning from the inside of row two over Dalton Pipgras and Matt Cogley.
