Scotland's Hannah Miley has put thoughts of retirement on hold to chase a "dream" of competing at a fourth Olympic Games at Tokyo 2020.
Miley, 29, reached the 400m individual medley final at the 2008 Beijing Games, London 2012 and Rio 2016, finishing sixth, fifth and fourth respectively.
The double Commonwealth gold medallist is recovering from ankle surgery and will miss much of the 2018 season.
"If I was to retire I'd kick myself for not trying to go for Tokyo," she said.
Talking to BBC Scotland, Miley, who has been given a recovery timescale of six months to a year, added: "I'd like to give myself the opportunity to at least try.
"The Olympic trials for us are next year. If I was to retire and take a step back, I think I would be kicking myself at not taking the opportunity to at least try and go for a fourth Olympics. But I need to make sure that I don't rush it."
Miley missed out on a third Commonwealth gold in April last year, finishing second behind England's Aimee Willmott, in the 400m individual medley before picking up a bronze medal in August's European Championships in Glasgow.
Shortly after collecting the 14th European medal of her career, she was dropped from British Swimming's World Class Performance Programme for 2018-19 before having the ankle operation.
Glasgow will stage the European Short Course Championships from 4-8 December and Miley will hope to compete in front of a home crowd again, having been announced as an ambassador for the event.
"It's fast, it's furious, it's exciting," she said. "For us as a host nation it's a great opportunity for our next generation swimmers to try and make the team.
"Tollcross has hosted some incredible events in the past; the European Championships, the Commonwealth Games, the Duel in the Pool. The home crowd makes a huge difference to the athletes competing so Britain will have a great chance of performing at our best."
