thirteen pounds to Parole. An outsider named The Bear set off in front and at one stage opened up a lead of two hundred yards. Isonomy finally caught up with the front-runner in the straight and pulled away in the closing stages to win easily by three lengths, with Parole third A few days later on 6 August he was sent to Brighton Racecourse for the two-mile Brighton Cup, in which he carried 136 pounds and started at odds of 1/10 against three opponents. After settling in third place he moved into the lead in the straight and went three lengths clear, before being eased down in the closing stages to record a three-quarter-length win over Paul's Cray. Isonomy was then sent north for the Ebor Handicap at York on 27 August, for which he was made 8/11 favourite. Despite the very difficult conditions ("mud and water flying in all directions"), and conceding at least thirty pounds to his opponents, he won impressively by eight lengths. In September he attempted to become the first horse to complete the stayers' Triple Crown in the Doncaster Cup, although there was some disappointment that the undefeated Hungarian mare Kincsem was ruled out of the race by injury. In a rough race he defeated the filly Jannette, despite being badly cut by the spurs of the runner-up's jockey, Fred Archer when he moved up to challenge for the lead along the rails. The Duke of Portland said of Isonomy's performance marked him as "one of the best and gamest horses that ever ran".

On his final start of the year he carried top weight in the Cesarewitch Handicap at Newmarket on 7 October. In this race, however, he was not expected to win, and seems to have been entered mainly to provide assistance to his owner's other runner Westbourne. He was not even included in the betting for the race. The plan failed, as Westbourne finished second to Chippendale, with Isonomy in fourth. 1880: five-year-old season Isonomy ran twice as a five-year-old and won both his races. On 19 May he carried 138 pounds in the Manchester Cup over one mile five furlongs. He was set to give large amounts of weight to many top-class horses and was not among the favourites for the race, starting at odds
