DOUBLE Olympic medallist Jazz Carlin is looking to write herself into the history books by being the first woman to win a medal both in the pool and in open water events at the same Olympics.

The Swindon swimmer, who now lives in Bradford on Avon, claimed silver in the 400m and 800m freestyle at the Rio Olympics last year but has revealed she plans to attempt marathon swimming.

The new event will see her get out into open water over a distance of 10k and the 27-year-old, who trains at the University of Bath, also hinted she may enter the new 1500m race at the Tokyo Olympics in 2020.

Carlin aims to take part in her first marathon next week at the FINA World Cup in China and told BBC Sport she was suffering from ‘Olympic Blues’ after Brazil.

"At times winning the two medals doesn't feel real - it was the best experience of my life, but then I realised it was over," she said.

"People talk about the post-Olympic-blues, but until you've been there and gone through it you don't understand.

"Ever since missing London 2012, reaching Rio had been my focus; I just wasn't prepared for how much it was going to take out of me and I felt a bit lost after."

The former Tigershark hopes the change will give her a renewed sense of purpose, having first dipped her toe in open water last summer at an open session in Radstock near Bath.

"Sometimes it's really cold here and people do think I'm quite nuts, but it's refreshing and I'm loving every minute of it," said Carlin.

"I've only done two races, but one in Wales was a quite brutal introduction as people were swimming over me.

"I was nervous, but I haven't felt like that for years and it was actually quite exciting so I want to keep testing myself and see what I can do."

If Carlin is able to claim a medal in both events, she will be the first woman to achieve the feat.

However, the 27-year-old is more than aware she will have to strike a perfect balance to be competitive.

"The danger with training for the longer distances is you can lose the speed you need for the shorter ones,” she added.

"I think I have a really great opportunity to be a part of open water and still try and get on that pool team, and it's quite exciting to think that you could make history in an event.”
