London 2012 Olympics: Team GB's rowers continue fine form in Belgrade as they sharpen race skills All agree they will probably continue tinkering with the line-up in the weeks to come after today's final. "For us it's just about getting into a rhythm and establishing a dominant pace in the middle of the course," said James. The Greeks aren't going to be slow [today], and I'm sure they will carry a few people with them. Lightweight double scullers Zac Purchase and Mark Hunter were a fraction slow off the start, but swiftly moved to the lead, and on a day of fluctuating tailwinds, were only four seconds off world record time without needing to sprint. The pair of Helen Glover and Heather Stanning resisted the urge to start too hard and rowed to a controlled victory over a pack containing former champions Romania, also within a few seconds of the record. Without New Zealand, a solid win today would show they are on track. Testing has thrown up a new men's double this year, and Bill Lucas and Sam Townsend set a marker when they won on Friday. A semi-final repeat was a step too far with former world champions Germany winning out. The new British duo, who were level with the Germans for most of the course, lost by only half a second and will be up against them today, with the added challenge of frequent medallists France. Single sculler Alan Campbell was under instructions to qualify for the final with as little effort as possible, and carried them out to the letter, allowing Lithuania's Mindaugus Griskonis to use up energy on a showy victory while Campbell and Czech Ondrej Synek kept their best under wraps. The most encouraging Olympic-class performance was that of George Nash and Will Satch in the men's pair. Selected to join the British team over several former silver medallists, the duo came to Belgrade ready to find out how fast they were on the world stage. Drawn away from the quick crews Germany and Greece, they have now won their head and semi-final, and are ready to take on the bigger challenges today. There were a couple of greyer moments: the new line-up for the men's quad was beaten, albeit in a strong semi-final, and single sculler Rachel Gamble-Flint, who is hoping to take the last place for London, was sixth in her semi. She now has two weeks before the qualification regatta in Lucerne.
