IMSA SportsCar Championship

The WeatherTech 240, also previously known as the Paul Revere 250, was a sports car race held on the road course at Daytona International Speedway on or around Independence Day, the same weekend of the NASCAR Cup Series' Firecracker 400. It has been held off-and-on over the history of that event, either the same night, or a couple days before. Traditionally, the race was held late at night, and finished in the early morning hours of the next day. The theme of the race was based on the famous "Midnight Ride" of Revolutionary War patriot Paul Revere. In 2020, due to the COVID-19 pandemic, IMSA reorganized their schedule. They announced they would be resuming their season at Daytona with an evening race on July 4, marking the return of summer sportscar racing at Daytona. The race was named the WeatherTech 240, with a duration of 2 hours and 40 minutes, and was to be held in front of a limited number of spectators.
