"Ruffian was undefeated in her first ten races, covering distances from 5.5 furlongs (1.1 km) to 1.5 miles (2.4 km), with an average winning margin of 81⁄3 lengths. She won her maiden race in record time by 15 lengths. She was on the lead at every point of call in every race she ever ran. She set a new stakes record in each of the eight stakes races she won. She also equaled two track records."
