“In all aspects, the 64th Rolex 24 At Daytona was an all-time event,” said IMSA President John Doonan. “I’m humbled, honored and blown away by the incredible efforts of our staff, teams, manufacturers, drivers, partners, our teammates at Daytona International Speedway and most of all our fans, who contributed in so many ways to what was a record-setting WeatherTech Championship race at Daytona and start to our 2026 IMSA season.”
Added IMSA CEO Ed Bennett: "Over the past several years, we’ve followed a clear and intentional strategy to grow the IMSA brand, elevate the event experience and broaden how fans can engage with us — whether they’re at the track or watching through modern linear, streaming or social platforms. To see every one of those areas trending upward is incredibly rewarding. I’m proud of our entire community for helping drive this remarkable renaissance period of growth in sports car racing.”
