Rennsport I was held at Lime Rock Park in Connecticut in 2001. It would only be held there one year. It was presented by both Porsche Cars North America and Brian Redman’s Intercontinental Events, Inc. Previously, in 1998, for the 50th anniversary of Porsche, there were two significant Porsche events. The West Coast had the Monterey Historics vintage racing weekend. Porsche and Watkins Glen hosted the 50/50 race weekend on the East Coast. The 50/50 celebrated both 50 years of Watkins Glen and Porsche.
