PICK OF THE DAY: Open Water Swimming Women's 10km Marathon

Keri-Anne Payne won Britain a silver in Beijing - now she's aiming for gold in Hyde Park's Serpentine

Equestrian: Individual Dressage Grand Prix

12:30pm BBC Olympics 5, BBC1

Britain had never won a dressage medal at the Olympics until this week, but they should get a second and perhaps more today. All three Team GB riders, who won the team event on Tuesday, were inside the top five individual riders at Greenwich Park. Charlotte Dujardin led the field and broke an Olympic record along the way; Carl Hester and Laura Bechtolsheimer were third and fifth respectively.

Whereas previous rounds were purely about performing standard moves with grace and precision, today's Grand Prix Freestyle - which alone decides the medals - is more expressive. It's the only round of the competition where routines are set to music, chosen by the competitors.

Reigning European champion Adelinde Cornelissen from the Netherlands is the main danger and has been the star rider - along with Dujardin over the past year.

Sailing: Men's 470 Medal Race

1:00pm BBC Olympics 4, BBC1

Again the Australians are a shoo-in for the gold. They always win the world championships, but they’ve only recently won an event in Weymouth — an important hoodoo to break. They told me afterwards that it didn’t matter to them, but I bet it did.

The Australians are just a little bit faster than everyone else. Their big tussle will be with the French and the British. Team GB’s Luke Patience and Stuart Bithell won silver at the 2011 world championships and I expect them to medal here. Considering it’s their first Games, I don’t see many nerves. Shirley Robertson

Women's Boxing Finals 

From 4pm BBC1, BBC Olympics 9

The first ever Olympics finals day for women boxers - and GB has one fighter left in. Nicola Adams, the flyweight, is guaranteed at least silver but will fancy her chances of becoming the Olympic champion after two deeply impressive performances in previous rounds. Standing in the 29-year-old's way is Cancan Ren of China.
