Barrow, European champion in 2014, is determined to try and secure one of the two Great Britain individual women’s platform spots up for grabs for Rio after seeing her successful synchro partnership with Tonia Couch broken up by British officials.
After Barrow was injured last year, Couch was paired up with Leeds teenager Lois Toulson.
Although Barrow was reinstated for the FINA World Cup in Rio where she and Couch won a bronze medal and secured Great Britain an Olympic quota place, Toulson has since been picked for the World Series.
Barrow, though, is using her disappointment to fuel her individual ambitions.
She recently said: “I’m going to fight like I’ve never fought before to be on the plane to Rio.
“At the moment, I feel stronger, fitter and more determined than I ever have done.”
The British Championships, which will act as the Olympic trials, take place in Sheffield between June 10 and 12.
Barrow, who has been training in Leeds in recent weeks, is determined to be in the best form of her life for those trials.
Diving in Puerto Rico will give her some much-needed competitive practice, which she is missing not competing in the World Series.
The qualifying and semi-finals in San Juan will take place on Friday, with the women’s platform final scheduled for Sunday.
