JAZZ Carlin admitted she was left with bittersweet feelings after being crowned 800m freestyle champion at the British Swimming Championships in Glasgow last night.

The Swindon swimmer, who now lives in Bradford on Avon, wrapped up her second national title of the week - following her 200m victory on Tuesday - touching home in 8:27.49 ahead of home swimmer Camilla Hattersley and Keri-Anne Payne.

However, the 25 year old’s time at Tollcross International Swimming Centre was nearly five seconds outside the Olympic qualifying standard, and not even within the two percent threshold for consideration for an individual spot, as well as being considerably slower than the 8:18.15 she clocked when winning World Championship bronze in Russia last summer.

The selectors can still use their discretion and as a world medallist Carlin may yet get a chance, especially as she will likely travel as part of the 4x200m freestyle relay team.

However, the bigger issue was her failure to deal with her nerves in the build-up to what are her fourth Olympic trials.

She said: “It’s difficult. When I come in here I want to be at my best to get on that Olympic team.

“It’s been a tough couple of weeks.

“I’ve put a lot of pressure on myself to not miss out on something like the Olympics which four years ago, it was heartbreaking for me.

“So it’s been tough and I just didn’t feel myself when I was racing there.

“When you’re racing a bit tense you can get a bit heavy and you don’t really get into your stroke.

“I’m trying not to focus too much on times. I looked at the time and was disappointed not to have gone a bit quicker but I did the best I can, that’s the best I had.

“I am normally the athlete that absolutely thrives on those big races but it feels like a bit of déjà vu coming back to the Olympic trials again and I did not want to miss out.

“So it’s something to discuss with all the great support staff I’ve got around me and try to make sure I can relax going into the 400.”

Next up for Carlin is the 400m freestyle tomorrow, where she will have a final chance to get within the qualifying standard.

Having finished fourth in the event at last year’s World Championships, Carlin is determined to get it right both in that race and in Rio if selected.

She added: “I have to make sure that come Saturday I put on the best performance I can then.

“I know I’m a lot faster than the times I’ve done and it’s about getting through this week and hopefully I can get myself in that Olympic team.

“I’m not one of the young ones anymore and I want to get to my first Olympics so it is tough so I need to go out there, do the best I can and hopefully get on that team.

“There are a few things I would like to change so it is about hoping from this week I’m on the team and I can make those changes for later in the year.”
