Myles, 29, joined the Tigers for the 2014 season and took the second-year Hampden league club within inches of a debut finals series.

The former SANFL player announced his decision to walk away from the second year of his coaching contract at Portland’s best and fairest count on Friday night.

He said it was only fair to the club that he relinquished the role.

“I have been going through a tough time for a few months now, with some personal issues,” he said.

“I am not in the frame of mind to put in the time, effort and energy required to coach at this level.

“I had to put the club first and this time of year is the hardest as coach.

“People say you can have a break now but that’s not the case. There’s pre-season planning, trying to recruit players and retain players.”

Myles said he had a passion for coaching and did not rule out a return to the caper in coming years.

“I really want to coach but I want to do it right,” he said.

“I could have floated through next year and then called time but obviously I have to get myself right first.

“I know I have made the right decision.

“I want to thank the footy club for the opportunity and the support they’ve given me this year.”

Myles, who will spend a month overseas in December, said he was unsure if and where he would play next season.

He said if he remained based in the south-west he would play for Portland, where he combined well with best and fairest winner Jake Dignan and runner-up Luke Crane in the midfield this season.

A move interstate is another option. Myles said Portland had a healthy list which could push for a finals spot in 2015.

The Tigers finished sixth on percentage under Myles, who moved across from North Warrnambool Eagles in the off-season.

“Whoever does take over has a nucleus of a fantastic side,” Myles said of the Portland list.

“We weren’t that far away this year. We had the second- most scoring shots and a lot of kids coming through.

“I blooded a lot of kids this year.” Portland now joins Cobden and Port Fairy as clubs searching for coaches for next season.

Camperdown last month appointed ex-Redland skipper Phil Carse and South Warrnambool turned to former premiership mentor Nigel Kol to lead their respective senior sides.

Warrnambool, Koroit, Terang Mortlake, North Warrnambool Eagles and Hamilton Kangaroos will enter next season with their 2014 leaders at the helm.
