Welsh swimmer Jazz Carlin says she was pleased with her time despite losing her European 800m freestyle title.
Carlin, double gold medallist at the 2014 European Championships, had to settle for silver in London.
The 25-year-old was five seconds outside her personal best, but it was an improvement on her time at April's British trials.
"I would have liked gold but I raced tough and it's faster than the trials," she said.
"The Olympic trials wasn't the best competition that I've ever done. It was a bit up and down and I was feeling tense, nervous. It was a pretty hard competition for me.
"To come here, enjoy it, see the crowd and it's just amazing to be in the mix and come away with a silver."
Carlin lost her European title to Hungarian Boglarka Kapas, with Tjasa Oder of Slovenia claiming bronze.
Commonwealth champion Carlin had already secured her place in Team GB's team for this summer's Olympics in Rio.
Former Olympic silver medallist Sharron Davies says Carlin needs to believe in herself if she is to succeed at the Games.
