Road America Announces Featured Marque for the Weathertech International Challenge With Brian Redman in 2023


ELKHART LAKE, Wis., – August 23, 2022 – Road America recently announced that the Kastner Cup would be the featured marque of the 2023 WeatherTech International Challenge with Brian Redman. Widely known as one of the largest vintage racecar gatherings in the United States, featuring over 50 classes of cars racing in several groups, The WeatherTech International Challenge with Brian Redman will return on July 13-16, 2023. A mid-summer classic including everything from a special Concours on Friday and Saturday along the streets of Elkhart Lake and a special Triumph sports car racer reunion makes the 2023 event a can’t miss spectacle for any racing enthusiast.

“This event has become an annual tradition for hundreds of racers, enthusiasts, and thousands of fans every year,” said George Bruggenthies, Senior Consultant for Road America. “We are extremely proud to announce that the event will pay tribute to Triumph sports cars and the Kastner Cup experience, as drivers can imagine themselves as Paul Newman as they round Canada Corner, and spectators can smell the tires and race fuel just as they might’ve done decades before. Road America is poised to usher in the celebration with a racer’s reunion, races for club and pro series–vintage, historic and contemporary racers; a Concours with expert and people’s choice awards, track touring, parade laps, and a vendor marketplace, making the 2023 WeatherTech International Challenge with Brian Redman an event that everyone of all ages can enjoy.”

Having the Kastner Cup for Triumph sports cars serve as the featured mark for 2023 is a fitting tribute for the event as Triumphs have raced at the fabled four-mile 14-turn circuit since the late ’50s. The Kastner Cup was named in recognition of the career accomplishment and legacy of R.W. “Kas” Kastner, who passed away on April 11, 2021, at 92. Kas Kastner was one of the most influential individuals responsible for the racing success of Triumph sports cars from the late 1950s through 1970 and beyond. To this day, his series of Competition Preparation Manuals are a must-read for competitors in Triumph sports cars. Later in his career, Kastner directed the Nissan IMSA GTP team that won the manufacturers’ championship three years in a row and the drivers’ championship four years in a row; a remarkable achievement.

The Kastner Cup has become a major event on the vintage racing calendar for British car fans. The race is held at a different track each year to provide Triumph racers across the country a chance to compete for the Cup. Open to race prepared Triumph powered cars, the Kastner Cup is awarded to one competitor based on the following criteria:

• 50% for the competitive results on the racetrack during the event (not necessarily the winner)

• 25% for the presentation of the car

• 25% for the attitude and interest in Vintage racing

More details for the 2023 WeatherTech International Challenge with Brian Redman, including entry information, qualifying procedures, concourse information, and tickets, are expected in the coming months.
