About Thunderhill Speedway

Door county in the summer time and images of sunsets on the bay, sandy beaches and quaint shops come to mind. But to many, a Door County Summer also means fast cars and fierce competition at Sturgeon Bay’s Thunderhill Speedway.

Dormant for nearly a decade, the speedway roared back to life in 1993. Each Saturday night from mid-May through September, an average of nearly 100 race teams congregate at the Door County Fair Park on Sturgeon Bay’s East side to vie in four competitive classes.

The 6:00 p.m. start time is especially popular with families offering a chance to see a complete show and still get back home at a reasonable time. The Speedway features two classes sanctioned nationally by the International Motor Contest Association (IMCA), the IMCA Modifieds and IMCA Stock Cars, and regularly feature drivers that have ranked in the top 20 in the country.

The Street Stock and Bomber divisions round out the show as the Speedway’s entry level classes. Door county drivers share the spotlight with drivers who make the trip each weekend from throughout northeastern Wisconsin. The Speedway itself has seen a transition since it reopened. Fans will be treated to a brand new, handicapped accessible, cover grandstand in 1999. The pit area and parking lot were completely redone in 1998 making for a very fan friendly environment.

The wide, semi-banked third, mile clay oval offers three wide action and plenty of places to pass leading to an exciting show from start to finish. The Door County Fair Park is located on 14^th Avenue near the Cherry Point Mall in Sturgeon Bay, WI.
