Which were the longest-priced winners of the Kentucky Derby?

Run annually on the first Saturday in May, over a mile and a quarter, on dirt, at Churchill Downs in Louisville, Kentucky, the Kentucky Derby is the first leg of the American Triple Crown. The race was founded in 1875 by Colonel Meriwether Lewis Clark Jr. and based on the Derby at Epsom, which had already been in existence for the best part of a century. Indeed, the Kentucky Deby was originally run over a mile and a half, the same distance as the Epsom Classic, before being shortened to the current yardage in 1896. Three-year-old colts, fillies and, unlike the Derby, geldings are eligible to run in the Kentucky Derby.

The Kentucky Derby is a Grade 1 stakes race in which colts and geldings carry 126lb, or 9st 0lb, and fillies receive a 5lb weight-for-sex allowance, such that they carry 121lb, or 8st 9lb. The race is a test of class, such that long-priced winners are few and far between. The longest-priced winner of the race nicknamed “The Run for the Roses” was, in fact, Donerail, bred, owned and trained by Thomas P. Hayes and ridden by Roscoe Goose, who in 1913 belied odds of 91.45/1 when beating favourite Ten Point by half a length. Second on the all-time list comes Giacomo, trained by John A. Shirreffs and ridden by Mike Smith, who in 2005 was returned at 50.3/1 when, coincidentally, beating another favourite, Bellamy Road, by the same margin.
