Martinsville speedway, site of this Sunday's NAPA 500, is the smallest oval on the Winston Cup tour, only .526 of a mile. Bobby Hamilton, a short-track specialist who won the Goody's 500 there in April, explains the tricks of winning on a bullring.
You brake from 140 mph on the straightaways down to 60 in the turns. To win, you must avoid burning up your brakes. One way is to bank off other cars—drive inside them and literally bounce off them—through the turns. Although such low speeds feel fast because the track is so short, you try things you wouldn't dare do on superspeedways. When somebody blocks me, I might drive right over a curb to pass him.
