MBNA America 400 call Dover Downs International Speedway home. This monster mile is NASCAR's only true oval track. Richard Petty won his first race in Dover in 1969. He and Bobby Allison have the most career wins at Dover with seven each.
Races at Dover were originally 500 miles, but that proved to be too exhausting for many drivers. Even still, when shortened to only 400 miles, drivers climb out of their cars rather weary. You'd think a sweep of the two races at Dover in a season would be hard to come by. But, when a team figures out how to win at Dover, they can easily win it a second time.
