The world’s oldest continuously operating motorsport facility, the Milwaukee Mile boasts more than a century’s worth of history. While the track honors its history each year with the Millers at Milwaukee Vintage Indy Car Event, it’s the challenge of getting modern racing cars around Milwaukee’s barely banked corners that makes every race day at this Midwestern fairground oval another page in the history book.

From its opening in 1905 the Mile has been home to open-wheel racing cars – for the first 49 years as a dirt track and since 1954 as a paved one. For more than 60 years Milwaukee served as the next stop on the IndyCar circuit following the Indy 500, where drivers who had bad race at Indy got another shot at glory.  Over the years the Milwaukee Mile has also played host to USAC’s Silver Crown cars and Midgets as well as NASCAR, ARCA, ASA and the Mid-American Stock Car Series. The track has been re-scanned for 2026, adding a road course layout to its traditional oval layout.

Located outside the picturesque village of Elkhart Lake, in Wisconsin’s beautiful Kettle Moraine region, an hour north of Milwaukee and just two hours from Chicago, Road America opened in 1955. From 1950 through 1953 the town had been host to annual sports car races conducted on ad-hoc circuits made up of linked sections of county highways, but safety concerns ended open-road racing. The track was built by local civil engineer Cliff Tufte, who set out a 14-turn, four-mile ribbon of pavement, literally over hill and dale. Tufte took advantage of the hillsides adjacent to many parts of the track to provide natural viewing areas for spectators.

Road America, one of the world’s classic road-racing venues, has been host to every important North American racing series, beginning with SCCA sports cars in the 1950s, to the Can-Am and Trans-Am in the ’60s and ’70s, IMSA’s GT and GTP cars since the ’70s, and IndyCars beginning in 1982. NASCAR ran a race at Road America in 1956, won by the legendary Tim Flock, and now includes the Wisconsin road course on its Nationwide Series schedule. The June Sprints, put on annually for more than 50 years by the SCCA’s Chicago Region, draws 600+ amateur sports car racers and as many as 30,000 spectators. The current schedule also includes vintage and motorcycle racing.

The Mid-Ohio Sports Car Course ranks among America’s premier road racing facilities. The track has hosted every major American road racing series worthy of the name, and the list of drivers who have stood atop Mid-Ohio’s victory podium is a Who’s Who of racing greats.

In its near-fifty year history, Mid-Ohio has hosted America’s premier racing series including the United States Road Racing Championship, Can-Am, Trans-Am and Formula 5000, along with IMSA, IndyCar and NASCAR races.  As well, Mid-Ohio has long been a club racing mecca and enjoyed a 12 year run as the home of the Sports Car Club of America’s National Championship Runoffs from 1994 through 2005. For 2026, iRacing has rescanned and rebuilt Mid-Ohio from the ground up.
