Usain Bolt is planning to continue his career as a long jumper if he is successful in retaining his 100 metres and 200m titles at the 2012 London Olympic Games.

The 23-year-old Jamaican has again denied he is planning to step up to the 400m but instead announced he would like to compete in the long jump discipline at the 2016 Olympics.

‘I'm hoping not,’ Bolt replied to the frequently asked question about stepping up to the one-lap event. ‘If I win the sprint races in the 2012 Olympics in London I will try the long jump at the following Olympics.

‘I will have to retire (from sprinting) because people will be sick of seeing me win. I'm hoping I don't lose because if I did I would have to try and redeem myself.’

Bolt tonight competes at the Samsung Diamond League meeting in Lausanne for the first time in six weeks after injuring an Achilles tendon in his last race where he won over 300m in Ostrava.

However as a precautionary measure he has withdrawn from the 200m and the organisers at very short notice have arranged a low-key 100m outing.

Bolt said: ‘The doctor said to me I should avoid running the curves, so that's why I'm actually running the 100. I have no idea whether I am in good shape or not.

‘The doctor says the injury is getting better, so that is great news and what matters most. However I should still avoid curves. In four weeks I should have fully recovered.’

Bolt admits his vulnerability could allow his arch-rivals notably countryman Asafa Powell and Tyson Gay of the USA to defeat him although he believes the former is the likeliest to pull off the feat.

‘Well for Asafa certainly, but Tyson is struggling with injuries as well,’ he said. ‘But if Asafa beats me I definitely won't say it is due to my injury.’

The duo are due to go head to head over 100m in the eighth leg of the Samsung Diamond League series at the Stade de France next Friday.

The Lausanne meeting will offer another final chance for British athletes to sharpen up against much tougher opposition than they will encounter when the European Championships get under way at the end of the month.

World silver medallist Lisa Dobriskey faces an awesome 1500m field as does Dai Greene in the 400m hurdles where, with conditions expected to be perfect, he should lower his personal best.

Michael Rimmer competes over 800m, Andy Turner is in the 110m hurdles and they are joined by high jumper Samson Oni and Barbara Parker who set a 3000m steeplechase personal best in Eugene on Saturday.
