Dwain Chambers fully expects to come away from the EnBW Weltklasse Biberach international meeting tomorrow with the Olympic 100 metres 'A' qualifying standard.

Chambers ranks that as his top priority before his solicitors take legal action to try to overturn a British Olympic Association (BOA) lifetime ban preventing former drug cheats from competing not only in Beijing but at future Games.

The 30-year-old Londoner would almost certainly have achieved the required time of 10.21 seconds a fortnight ago but a strong headwind spoilt his attempt at Crystal Palace.

His victory in a time of 10.24secs into a very strong wind of 1.8metres/second, was probably worth 10.1 according to track statisticians at the meeting.

Now Chambers has gone abroad to an international meeting in southern Germany, where the weather forecast should offer almost perfect conditions, in his quest for the qualifying time.

"I'm very confident about what shape I'm in and it's just a matter of putting the right race together in the right place at the right time," he said after his last outing.

Chambers won silver in the 60m at the World Indoor Championships in March before attempting to embark on a career in rugby league, which because of his lack of experience did not materialise.

"My training's improved for the sheer fact that I've obtained a lot of fitness from the rugby and I suppose working differently, it's paying dividends now," he added.

Chambers has, for the present, distanced himself from the legal proceedings his lawyers are preparing in his bid to have the BOA bylaw rescinded.

"That's not my field," said Chambers. "I'm confident what I can do on the track and they're confident they can do what is necessary off it."

Chambers, who will also compete over 200m in Biberac, faces primarily German opposition in the shorter sprint, although Ernest Wiggins - who is surprisingly foregoing the USA Olympic trials, which start today - will also be in the field.

The fact there will be preliminary heats before the 100m final will also work in his favour, giving him the opportunity of a worthwhile warm-up.

Kelly Sotherton and Jade Johnson are also among a small contingent of British athletes taking the chance to complete their preparations before the UK National Championships, incorporating the Olympic trials, which begin in Birmingham on July 11.

Sotherton has proved in recent weeks she is fully recovered from the kidney infection that has effectively prevented her contesting a heptathlon before challenging for the gold medal in Beijing.

To counter missing the Gotzis combined events meeting at the end of May, the 2004 Games bronze medallist has since contested different disciplines and tomorrow will compete over 200m and in the 100m hurdles.

Last Sunday, Sotherton showed her versatility by playing her part when the British women's team were an excellent third in the European Cup in their first year back in the premier tier following relegation.

Sotherton ran a fast anchor leg in the final event, the 4x400m relay.

"I never thought I would have been in shape to run 51 seconds," said the multi-eventer. "I was really nervous before it started and worrying for the team in case I let them down.

"But I'm fit and I wouldn't be running if there were any doubts," she insisted.

Johnson, after flying out to a new long jump personal best of 6.81m in Annecy, has a further chance to show she has regained the form that melted away after her seventh place at the last Olympic Games.

Indeed, the 2002 Commonwealth and European silver medallist's loss of form saw her lose lottery funding after being excluded from UK Athletics' World Class Performance Plan at the end of last year.

Johnson again locks horns with Lyudmila Kolchanova, who pushed her into second place at the European Cup by leaping a world-leading distance of 7.04m at the French venue.
