This is one of my favorite events to read about and one day I will do this. Here is the link to the story from Car and Driver.

Most teams end up getting less than 4 hours of sleep a night and it really becomes an endurance race. This race is based on the original Cannonball Race put on by Brock Yates in 1971. Good times and good stories.
