Rushaway was bred by the prominent Thoroughbred owner, breeder and Hialeah Park Race Track proprietor Joseph E. Widener at his Elmendorf Farm in Fayette County, Kentucky. Rushaway's sire was Haste, owned and raced by Widener and trained by Hamilton Keene. His race wins at age two included the 1925 Grand Union Hotel Stakes and the Saratoga Special Stakes. As a three-year-old in 1926, Haste had a third-place finish in the Belmont Stakes then went on to win the Withers Stakes followed by a gutsy win under jockey Earl Sande over Edward Bradley'sBagenbaggage in the inaugural running of the Fairmount Derby. Haste's sire was Maintenant, a French-bred son of William K. Vanderbilt's French champion Maintenon. Sent to the United States as a three-year-old, Maintenant was a powerfully built stallion who stood seventeen hands. A Daily Racing Form article described him as a 'whale'. Maintenant debuted at Aqueduct Racetrack and on July 11, 1915 won a mile race with ease. However, injuries limited his racing career. Rushaway's dam was Roseway, a daughter of multiple stakes winner Stornoway. Roseway won the 1919 1000 Guineas Stakes, a British Classic race for fillies run over a distance of one mile at Newmarket Racecourse. In the Epsom Oaks, the other Classic for fillies, Roseway ran second to Bayuda. Roseway was sold for breeding usage by her owner/breeder Sir Edward Hulton and in 1925 new owner Joseph Widener brought her to the United States to stand at his Kentucky stud farm.
A "Very Remarkable" and "Unparalleled" racing feat
Rushaway's back-to-back wins in a two-day period was and remains a most noteworthy achievement which the Daily Racing Form reported was "a feat without known precedent in this country or abroad." The accomplishment was made even more remarkable because Rushaway was carrying top weight in the eight-horse field by three pounds yet won by 6 lengths and did it in a new race record time for the mile-and-a-quarter distance. The DRF pointed out that while many had their concerns about the wisdom of racing the horse in such a manner, everyone agreed that Alfred Tarn was an astute horseman and someone they held in high esteem. Rushaway's victory in Latonia marked his third Derby win of the year. On June 29, 1936, Rushaway won the Middlesex County Handicap at Suffolk Downsin Boston, Massachusetts.
1937 - 1942
As a four-year-old Rushaway continued winning in a fast time, setting a new Lincoln Fields track record of 1:50 flat for 1 1/8 miles in the 1937 Marguette Handicap. Rushaway raced on through 1942 with only moderate success but still retired having finished in the top three forty-seven times in one hundred and seven starts.
