Endurance racing is somewhat common in auto racing, and a lot of comparisons can be made to marathon runners as opposed to sprinters. Endurance racing is not as popular in racing covered on TV because it takes a lot to watch cars go in circles for that long. But it’s a sign I can’t part of auto racing because it tests how well a car is built even more so that how fast it can go. So in many ways the pit crew are the bigger stars in endurance racing rather than the drivers.
One of the biggest endurance races is a 24 hour race in Daytona that took place right after the Ferrari Challenge race there earlier this year. In an endurance race a team can choose how many drivers to use. There are safety rules about minimums for switching drivers, but a team can switch out more often if they choose. During some pit stops, in addition to changing tires and refueling they switch drivers. The race Michael did counts how many laps each car completes in 14 hours. Some others race for the first to get to x number of laps.
So Michael rotated with several drivers but I have not seen a firm count on how many his team had in the 14 hours which started Saturday evening and went to Sunday late morning.

It's usually the reason why she doesn't attend every race..
