A poor NSW campaign and disappointing Jewels followed before he turned the corner and was outstanding in the Victorian winter, dominating the Australasian Breeders Crown.
Even after that he had looked more comfortable as a sprinter than a stayer until he produced a stunning performance to overcome an early gallop to win the Methven Cup on grass two starts ago.
All of a sudden he was among the NZ Cup favourites and seen as a genuine open-class force.
Until a week ago when he blew the start of the Ashburton Flying Stakes and learned that at the highest level such mistakes are punished.
So which Fly Like An Eagle will turn up today?
With the unique, congested nature of the Kaikoura track and its proximity to the crowd, it has always been a test for any horse whose manners are suspect.
That, coupled with the fact Fly Like An Eagle is going to be jammed up in the middle of the front line at the start, suggests punters would want around $4 to be backing him for any serious amount today, even if he is the most in-form horse in the race.
Purdon has plenty of back-up though, with Highview Tommy, Sushi Sushi and Major Mark also in the 2400m stand.
Highview Tommy is the ideal type for Kaikoura, with his bullet-proof manners and equine tractor racing style but he has lacked spark at the end of his races this campaign.
So that could leave Sushi Sushi as Purdon's best chance.
He has been luckless for a variety of reasons this season but looks suited to Kaikoura as he likes to race handy and the pace should be on.
Choise Achiever, as a Hunter Cup winner, comes in well under today's conditions while the big improver could be Jarcullmebra.
Champion I Can Doosit chases his 15th win on end in the day's main trot.
He was allowed to miss Ashburton last Monday, but trainer Mark Purdon says he is back to his best, which should see him down one of the Paul Nairn stablemates of Dr Hook or Stig.
