Historic Sportscar Racing (HSR) is North America’s premier vintage and historic racing series, celebrating the cars, sights, and sounds that define motorsport’s golden eras. Founded in 1977 with its inaugural event—the Walter Mitty Challenge at Road Atlanta—HSR has evolved into a vibrant community where legendary race cars return to the track and motorsport history comes alive. Now operating under the International Motor Sports Association (IMSA), HSR stages seven major events annually at world-renowned venues, including Daytona International Speedway, Sebring International Raceway, Michelin Raceway Road Atlanta, and Watkins Glen International.
