British swimmer Fran Halsall is determined to enjoy the Olympics this summer after feeling fatigued and under pressure at London 2012.
The 26-year-old freestyle star goes into her third Games as a double Commonwealth champion, but failed to live up to expectations at London 2012.
She finished fifth twice as Team GB won just three swimming medals but she now wants to be more relaxed at Rio.
The former Sky Academy Sports Scholar said: "I haven't got a newness to it of, 'Oh, it's going to be all amazing. It's all good'. I've put my hand in and got a little bit burnt.
"In that sense it's a bit harder. But I've got so much experience to draw on that if I take out the emotion from it and use the past two times as experience, then it's only going to stand me in better stead."
Merseyside-born Halsall, who swims for Loughborough, says the buzz of a home Olympics probably affected her performance.
She added: "The thing I learned from the London cycle is not to get too carried away with it too soon and get too excited, because there's only so much emotion you can expend on something."
Michael Jamieson and Rebecca Adlington won GB's only swimming medals in 2012 but Halsall says everyone will be raring to improve this time round.
She said: "You want to go to an Olympics and compete. You want to swim amazing, you want something incredible to happen there.
"It's easy to get caught up in that and forget that, 'I actually need to swim 100m and my best way of swimming it is this way'.
"The fact everyone on the team knows, 'This is how I need to swim my race, this is what I'm going to do', and we've been practising it this year, last year, the year before. It's all been put in place.
"Performances will come off the back of that."
Halsall will probably swim in the 50m and 100m freestyle as well as in the relays in what is her 10th year as a Team GB swimmer.
