Campbell-Brown stormed to a 21.98 200m victory on Saturday at the EAA Outdoor Meeting in Barcelona.

"Now all I need to do is stay focused and healthy," said Campbell, who in 2004 captured Olympic gold when she beat out American Allyson Felix with a time of 22.05.

"I know that things are going to be very competitive in Beijing and to accomplish what I want, I know I've got to stay mentally tough, but my morale on the way there will now be sky high," Campbell-Brown was quoted as saying on the IAAF website.

In Saturday's run, Campbell-Brown recorded her second fastest time ever, only behind her 21.94 done to win the National Championships. The time at the championships was the athlete's first sub-22 clocking of her career and came one day after she failed to secure qualification in the flagship event, the 100m. Despite running her second-fastest time ever at 10.88, Campbell finished in fourth spot behind new champion Kerron Stewart (10.80), Shelly-Ann Fraser (10.85) and Sherone Simpson (10.87).

Campbell-Brown, the bronze medal winner in the women's 100m at the Athens Olympic, was pleased with her performance on Saturday.

"It was a good run, I'm happy to come out here for my last 200m before the Olympics and run a very comfortable race," Campbell-Brown continued.

"I executed well and I now feel very confident, that was the whole objective, to end on a good note," said Campbell-Brown.

American teenager Bianca Knight was a distant second in 22.47. Ricardo Chambers won the men's 400m in a season-best 44.80 seconds. Chambers measured his run well to hold off Trinidadian former world junior champion Renny Quow (44.89).

Jamaican champion and former Commonwealth Games champion Michael Blackwood had to settle for fifth in 45.43.
