how fast can a greyhound run in mph
Greyhound It is a gentle and intelligent breed whose combination of long, powerful legs, deep chest, flexible spine and slim build allows it to reach average race speeds exceeding 64 kilometres per hour (40 mph).[3][4][5] The Greyhound can reach a full speed of 70 kilometres per hour (43 mph) within 30 metres (98 ft), or six strides from the boxes, traveling at almost 20 metres per second (66 ft/s) for the first 250 metres (820 ft) of a race.[6][7]
Kentucky Derby The fastest time ever run in the Derby was set in 1973 at 1:59.4 minutes when Secretariat broke the record set by Northern Dancer in 1964. Not only has Secretariat's record time yet to be topped, in the race itself, he did something unique in Triple Crown races: each successive quarter, his times were faster. Though times for non-winners were not recorded, in 1973 Sham finished second, two and a half lengths behind Secretariat in the same race. Using the thoroughbred racing convention of one length equaling one-fifth of a second to calculate Sham's time, he also finished in under two minutes. Another sub-two-minute finish, only the third, was set in 2001 by Monarchos at 1:59.97.[11]
