Editing Lonhro (section)

===Five-year-old season: 2003–2004===
In August 2003, Lonhro began his 5-year-old season with his second win in the AJC Warwick S-Gr2 (1,400&nbsp;m). Two weeks later, it was on to the Chelmsford S-Gr2 (1,600&nbsp;m) where he again won. The WFA [[George Main Stakes]]-Gr1 (1,600&nbsp;m) at Randwick and a rematch with Grand Armee was next. In a slowly run race, Lonhro defeated Grand Armee by three lengths, with a further two lengths to the previous year's winner, Defier, in third. It was then back to Melbourne for the [[Caulfield Stakes]]-Gr1 (2,000&nbsp;m), where Lonhro beat Mummify. Winning by two lengths, he became the first horse to win consecutive Caulfield Stakes since Kingston Town in 1981 and 1982.

Two weeks later, Lonhro looked invincible in the Cox Plate-Gr1 (2,040&nbsp;m) with recent stars Sunline and Northerly missing and only Defier and Fields of Omagh joining Lonhro from the 2002 field. There were doubts over Lonhro handling the Moonee Valley surface, but his class was expected to overcome any problems. Then, in the 40 minutes before the race, it began to rain, continuing through to the race itself. The track was dead but soggy. In the running, Fields of Omagh hit the lead around the turn as Defier challenged and Lonhro lost ground trying to balance up for the straight. In the straight, Fields of Omagh refused to give in to Defier with Lonhro closing down the outside. Fields of Omagh crossed the line to win by a long neck from Defier with Lonhro a half length away third. For the second year running, Lonhro had failed to run as well as expected in the Cox Plate. Critics claimed that the horse was a fair weather champion, dominant in small weight-for-age fields but unable to cope with the pressure of a larger field.

In 2004, Lonhro opened his campaign in the C.F. Orr S-Gr1 (1,400&nbsp;m) at Caulfield.  Inside the final 100&nbsp;m, he swept up on the outside to hit the front from Sound Action and Super Elegant as Vocabulary took a narrow run between them. Vocabulary lunged at Lonhro but he won by a half head with Sound Action third. Lonhro took on a similar field in the St George S-Gr2 (1,800&nbsp;m) two weeks later, winning eased up by 1½ lengths. He then lined up in his final race in Melbourne in the Australian Cup-Gr1 (2,000&nbsp;m) at Flemington.

The field featured some of the stars of the spring with Lonhro joined by [[Makybe Diva]] ([[Melbourne Cup]]), [[Mummify]] ([[Caulfield Cup]]), and [[Elvstroem]] ([[VRC Derby]]). Lonhro was pocketed 200 metres from home but got out and scored a narrow victory in the final stride, beating Delzao.

Lonhro returned home to Sydney for his last two races before retirement. Both Octagonal and Lonhro were known for arriving at the barriers, stopping with head up and looking for the winning post (closely monitored by the on-track camera), then calmly walking into the barriers. On 3 April 2004, Lonhro competed in his second George Ryder S-Gr1 (1,500&nbsp;m). His sire Octagonal (brought down from Woodlands Stud for the event) came into the mounting yard first, followed by Lonhro. Octagonal then led out the field, who then galloped down the straight as the field went to the barriers.

The field jumped, and Lonhro settled at the rear as usual. It was an evenly run race round the Rosehill track. In the final 100&nbsp;m, Lonhro started to race away, winning by 2½ lengths from Grand Armee with a further 1½ lengths to Private Steer, who won the Doncaster&nbsp;– All Aged Stakes&nbsp;– Gr1 double at her next two starts.

On the final day of the AJC carnival, Lonhro lined up for his final race start in his second [[AJC Queen Elizabeth Stakes|Queen Elizabeth Stakes]]-Gr1 (2,000&nbsp;m). Again, he settled near the rear, but Grand Armee's rider rode a tactically clever race, taking the lead and slowing the pace in the middle part, whilst opening up a large gap between himself and Lonhro. In the straight, the gap was to prove too great for Lonhro, and Grand Armee ran out the winner by six lengths.
