Great Britain's David Carry has booked his place at London 2012 after winning the 400m freestyle gold at the ASA National Championships.
The 30-year-old recorded a personal best time of 3:46.86s, ensuring that he will be representing his country at the Olympics for a third successive year.
"I've never been so emotional after a race before," Carry said. "This season more than any has been really quite tricky for me - I've had an injury and other things going on. So to come back to swim like that is just really incredible.
"And there was so much more caught up in it - knowing it is going to be my last Olympics, knowing my fiancee, my wife to be, is going to be there and I want to be part of that team too.
"It's just been an incredible journey this year - to compete like this at the last chance, the Olympic trials, is just incredible and at the age of 30 too. It's a dream come true."
Rebecca Adlington will have the option to join Team GB's 4x200m relay team after winning the 200m freestyle final at the ASA National Championships.
