Sanita Puspure says she is likely to call time on her career after Tokyo but hasn't ruled out hanging around a little while longer.
The Cork-based rower turned 39 in December and is targeting a podium place in the rescheduled Olympic Games next summer.
Having being denied at the quarter-final stage in London and Rio, the Latvian-born ace, who has since won single sculls gold at the European and World Championships (twice), has set her sights on Japan.
"It's definitely is an itch to be scratched," she told RTÉ Sport.
"There was a time last year when they didn’t know if it would be postponed or not, where I was kind of afraid I won’t get to scratch that itch, it’s the last cherry on the cake that I want to get.
"I’ve done everything else and I don’t want to just go to make up the numbers so yes, I don’t usually speak about this loudly, but I would be lying to myself if I said that anything else but a medal would actually satisfy me."
On the subject of whether or not it would be her swansong, Puspure said: "I’m saying yes, but then who knows?
"This time next year I might be singing a different song, maybe going for another couple of years, then the next term is only three years, I don’t know, we’ll see."
