BARCELONA: Britain`s Dwain Chambers and Frenchman Christophe Lemaitre are set for a much-anticipated showdown in the 100 metres at the European championships in Barcelona Wednesday.

Assuming both athletes, the only two in the field to have broken 10 seconds this season, make it through their semi-finals, they will go head-to-head in the Olympic Stadium at 8:45 a.m.

Chambers, who was stripped of the 2002 European title after admitting to doping, won his heat in 10.21 seconds Tuesday before Lemaitre recorded the quickest time of the night of 10.19 in the last of the five heats.

The fastest European this year after setting a national record of 9.98 at the French championships this month, Lemaitre said he had felt a twinge in an adductor muscle during the warm up but it had not impeded him.

"I am satisfied with what I did," the 20-year-old told reporters. "I did not relax at the end because it`s in my nature to win my races."

Other medals up for grabs Wednesday include the women`s long jump, 10,000 metres and discus and the men`s hammer. The day`s action opens at 7:05 a.m. British time with the women`s 20-km walk.
