THREE-TIME Olympic champion Ben Ainslie insists he is slowly building up a picture of what London 2012 will be like after another dominating day at the Weymouth and Portland International Regatta.

The 34-year-old has been in top form on England’s south coast during the London 2012 test event, and showed no signs of slowing down on Wednesday with finishes of first and second.

This means he is sitting pretty at the top of the Finn class, seven points clear of nearest challenger Pieter Jan Postma from Holland, with just two more races to go before Saturday’s medal race.

But Ainslie is adamant it is just as important that he gets a feel for the London 2012 venue ahead of what he hopes is a fourth visit to the top step of the Olympic podium.

“Wednesday was another good day, another windy day with tough with strong winds so very tough physically but the results were great,” he said.

“It was very challenging as well because we raced the first race on one course and then switched to another for the second and the results were very pleasing on both which was great.

“We sailed on two courses which we haven’t sailed on this season and I can see there is a lot to take away for London 2012.

“We have another two fleet races and then medal race after that and I am still feeling good and confident of finishing on a high.

“I am happy in terms of my performances, I had one sticky day but managed to come back and have sailed really well since but I need to make sure I have a good end to the regatta to finish the job off.”
