[5] On 2 March 1859 Jealousy carried 9 st 8 lb in the four-mile Grand National Steeplechase at Liverpool.
[6] At the York Steeplechase meeting she finished second in the Londesborough Great Handicap, one length behind winner Chance.
[7] In early May Jealousy started as the favourite for a Handicap Hurdle race at Manchester, but bolted and ended up finishing last.
[10] Later in the month she finished fifth behind winner Goldsmith (who won by 20 lengths) in the Grand Open Steeplechase at Warwick and Leamington.
As the field turned into the finishing straight Bannockburn (who had fallen at the third hurdle and been remounted) closed down Jealousy's lead, but she soon pulled away again to win by ten lengths.
She was reasonably close to the leaders in the early stages and took the lead from her stable companion Xanthus as the field entered the main racecourse.
By the time the field had got over Becher's Brook, Medora was leading from Master Bagot and Jealousy had moved into fourth place.
As the field approached Beecher's Brook for the second time, Yaller Gal took the lead, until she was challenged by Emblem, who in turn was followed by Arbury.
[17] Through her daughter Madame Colorado, Jealously was the direct female-line ancestor of Shining Way,[18][19] who won the Irish Oaks in 1912.
