When Cameron van der Burgh takes to the blocks in Kazan it will be his fifth World Championships.
The South African has already won seven world medals including two golds – both in the 50m breaststroke in 2009 and 2013 – as well as a silver and four bronzes.
Cameron has also competed at two Olympics, winning the two-length title in London three years ago in what was then a world record time.
When asked if Russia will be his final World Championships, the 27-year-old said: “I’ll see. It depends how I do, if I am still in the top then there is no reason to retire.
At the end of the day it’s your living, it’s your money.
“I don’t think I am going to quit now and especially because I am enjoying it.
“I did think about it last year but I have found renewed energy for the sport and enjoying it so as long as I am still swimming well and close to the top – I love the sport and would love to continue.”
Over the last year Cameron has seen fellow Arena swimmer Adam Peaty eclipse his world records over both 50m and 100m.
The pair are on very good terms and met for the first time at last year’s Commonwealth Games in Glasgow.
