Winchester's Julia Beckett will be heading for Beijing this summer.
She was one of 35 swimmers named in the British Olympic team yesterday at the conclusion of the seven-day trials in Sheffield.
But there was disappointment for the Isle of Wight's Darren Mew, who misses out on a third Olympics after finishing only fourth in the 100m breaststroke.
The selection of Beckett fulfils a lifetime ambition for the 21-year-old Loughborough University student.
She earned her place on the team after coming third behind the new and former British record holders in the 100m freestyle, Caitlin McClatchey and Fran Halsall, and sixth in the 200m freestyle.
But with only two places available in each individual event, she can expect to be restricted to her now customary role of relay swimmer.
Beckett, a life member of Winchester Penguins, said: "I've always wanted to go to the Olympic Games.
"I often think that I would like to have an individual swim but I seem to be the relay demon.
"But it's better to be in the team as a relay swimmer than not at all and I'm so pleased to be there.
"We have some amazing swimmers and a great team spirit and I'm really happy to be part of that."
Mew, 28, who has been training in Florida in recent months, showed little of the form which made him the third fastest breaststroker in history when he set his British record in 2004.
He went into the final fourth fastest with a heat time of 1:01.65, outside the Olympic qualifying time which three others achieved.
In the final Mew suffered twice over, finishing fourth in a slower time of 1:02.50 as winner Chris Cook (City of Newcastle) broke his record as the first Briton to go under a minute.
City of Edinburgh's Kris Gilchrist grabbed the other Olympic place while James Gibson, who swam alongside Mew in the 2004 Olympic final, also missed out in third place.
Mew, who now joins Beckett and the rest of the British team in Manchester for this week's World Short Course Championships, said: "I've had a tough four months with several things going on in my family life but it can't be helped.
"At the moment I'm trying to put this behind me and focus on the event in Manchester.
"When that's over, I shall sit down and have a good think about the future and make a decision as to whether I'm going to continue."
