About this event

A mid-summer tradition, the WeatherTech® International Challenge with Brian Redman at Road America, taking place July 11-14, 2024, is one of the largest vintage racing events in the United States. The WeatherTech® International Challenge road race features over 400 vintage and historic racecars competing across several days. 


The iconic Formula Ford racecar will take center stage as the featured marque for the highly anticipated 2024 WeatherTech International Challenge with Brian Redman at Road America. This momentous occasion will commemorate the 55th Anniversary of the Formula Ford racer’s illustrious history, paying homage to the legendary machines that have graced the track over the years. Formula Ford has long been revered as a breeding ground for aspiring racing drivers, nurturing talent and showcasing exhilarating competition. The 2024 event promises to be a fitting tribute to the remarkable legacy of these open-wheel racecars, highlighting their enduring impact on motorsport.


An additional feature that is sure to thrill participants and attendees is the Ragtime Racers exhibition. Dressed in period coveralls, goggles, and leather helmets, they bring the spirit of early racing to life while ensuring everyone's safety. The Ragtime Racers offer an immersive journey into history. Their pits feature a mesmerizing 100-foot diorama, replicating a race shop from over a century ago, complete with authentic tools, a forge, vintage equipment, and period-specific signage. 

Throughout the event, car owners and crew are on hand, ready to share their passion with spectators. Roaming docents provide insights into the cars, and photo opportunities, especially with kids, are actively encouraged. Each car boasts a display board detailing its rich history.One standout feature is the requirement for a "Riding Mechanician" who once pumped fuel and oil into the engine and spotted for overtaking cars. The Ragtime Racers are the only group where race organizers permit a "rider" in race cars on track, creating a once-in-a-lifetime experience for hundreds of guests, VIPs, and news media.At Road America, be prepared to step back in time and witness the Ragtime Racers' living tribute to motorsports heritage. It's not just racing; it's a captivating journey through history at America's National park of Speed.
