Papua New Guinea swimmer Ryan Pini is considering one last Olympic hurrah in Rio.
The former Commonwealth champion retired after competing in the London Games in 2012.
He returned to the pool a year later to prepare for last month's Pacific Games in Port Moresby, where he won seven gold medals and was named outstanding male athlete.
After extending his return for this month's World Championships in Russia, the 33 old year admits he's now pondering one last big challenge.
"Definitely on my mind. What I've done preparation wise with having my appendix removed and the birth of my son - two big things that happened within eight weeks of the lead-up to Pacific Games - if I can better that for next year, which I believe I can, and my whole idea is I really enjoy swimming so I'm going to compete up until the Olympics and if I'm improving from what I have now that's a pretty good incentive for me to go to Rio".
Ryan Pini has already qualified for Rio in three events but says if he doesn't feel he is performing well he will give up his spot for a fellow PNG swimmer.
