I think that Nascar sprint cup series has some of the best championship formats out there, and they have one of the hardest longest seasons out there. Yes i know they drive in circles and turn left for the most part, but doing it in 100 degree summer weather in a car that is up to 180 degrees inside, for 500 miles has gotta be one of the toughest feat an athlete could accomplish. Most poeple would probably faint and slam a wall.
