The gold medal is back on for Falmouth's Ben Ainslie after an excellent day's racing for the Brit in the finn class.

Ainslie won the opening day's race, with series leader Jonas Hogh Christensen finishing in eighth. The second race saw Christensen lead Ainslie for most the race, but the Brit fought back to claw a 70-metre deficit in the final downward leg to overtake the Dane and finish third overall.

It sees Ainslie cut the Dane's lead in the series to three points and considering that the gap, between Christensen and Ainslie, stood at 10 points this morning, it was a tremendous day for the Falmouth sailor.

The first race saw Ainslie start well. Rival Christensen tried to catch the British sailor, but capsized in doing so. 

Ainslie then stormed ahead of race leader Pieter-jan Postma, of the Netherlands, to take first place as Christensen finished to eighth.

In the second race Spain's Rafael Trujillo led for most of the race. Ben Ainslie was left trailing Hogh Christensen, in second, as he turned the bottom mark, thanks partly to a penalty turn he had to complete earlier in the race.

However, Ainslie showed great speed on the final downward leg to overhaul the Dane, who was 70-metres ahead of him. It was enough to give him third overall, behind Postma and Trujillo.

The points total from each race is tallied up at the end of the ten races. The top ten competitors can then discard their worse score, before heading into a medal race on Sunday, where the points count double.

It means, with a three point gap, if Ainslie can claw another point back on Hogh Christensen in tomorrow's two race and win on Sunday then he will get gold to become the greatest Olympic sailor of all time.
