Fastest horse in the world (Cogburn) works for Breeders' Cup Sprint

Hall of Fame trainer Steve Asmussen likes his horses to run fast when they race, not for a routine workout. So that was Cogburn - who in winning the Grade 1 Jaipur in 59.80 seconds set is believed to be the fastest time ever for 5 1/2 furlongs -- working an easy half-mile in 49.80 Monday right after the Churchill Downs track opened for training at 5:30 a.m. Cogburn last raced in easily winning Kentucky Downs' $2 million, Grade 2 Ainsworth Turf Sprint on Sept. 7. He is training up to the $1 million Breeders' Cup Turf Sprint at Del Mar Nov. 2. Video starts out with b-roll of Cogburn, including heading into and galloping out of his work, followed by Asmussen interview.
