2021 Rolex 24 field poses for group photo at Daytona

Spectators soaked in a peek at the array of prototypes and sports cars during last weekend’s Roar Before the 24 preliminary at Daytona International Speedway. But that was just a prelude to the twice-around-the-clock classic that opens the IMSA season, the 59th Rolex 24 at Daytona, which starts at 3:40 p.m. ET Saturday and ends at the same time Sunday.

The field assembled Wednesday at the 3.56-mile circuit for the traditional group photo before the 24-hour endurance event, capturing the lineup from multiple angles. The 49 entries are divided among five classes of cars competing for divisional wins and overall laurels.
