Norwich swimmer Anne Bochmann is putting all her eggs in one Olympic-sized basket, but she admits it will be tough with the queen of British swimming Rebecca Adlington standing in her way.

Bochmann will not compete before the British Olympic trials at the London Aquatics Centre in March, preferring to concentrate on training.

And the 400m freestyle specialist will have it all to do with double Olympic champion Adlington, and former world record holder Jo Jackson also vying for the two spots in the British team in London.

'I'm not racing again until the trials, it means I have to put in a lot of work in training,' said former Norwich High pupil Bochmann, speaking at the launch of the Swimathon Weekend – the world's largest fundraising swim – at the Hydro Swimming Pool in Harrogate.

'We're really in heavy training at the moment but I feel like it's going very well.

'I know it's going to be really tough to qualify. The 400m freestyle is probably the most competitive event in British swimming at the moment, but hopefully I can qualify for London.

'British swimming has really come on in the last few years and with the Olympics everyone is going to be even more up for it.'

Bochmann revealed the chance to compete at the Aquatics Centre where the Games will take place is an added incentive.

And while the 400m free remains her chosen event, she will also turn her attention to the 200m individual medley and the 200m freestyle to improve her chances of qualifying for London.

The 18-year-old added: 'Qualifying is going to be so tough, but you don't know what will happen.

'I haven't done much medley in the last year or so but I am doing some more work on it and I will probably compete in that at the trials, as well as the 200 free.

'It's going to be even more special with the trials taking place in the Olympic pool.

'There should be an incredible atmosphere and everyone is looking forward to racing there.'
