As a 2-year-old in 1886, the incredibly fast colt Tremont achieved the seemingly impossible: During a 10-week span, Tremont went undefeated in 13 starts, all of them stakes races, and was never headed at any point in those races. It was an unprecedented display of sheer speed and superiority, though unfortunately, Tremont was unable to return to the races the following year and had to retire unbeaten and virtually untested.
