Team GB are hoping to recover their winning streak later after a rare gold medal-free day.
Among the main contenders for a podium place today will be Nicola Adams as she competes in a historic first women's Olympic boxing final.
The flyweight will realise her 17-year dream as she takes on China's Ren Cancan at the ExCeL Centre in London.
It will be a key moment for women's boxing, which is making its debut at the Games.
"I've been training for this moment since I was 12 years old and to think it is finally here is just incredible," said the 29-year-old from Leeds.
After a rush of medal wins in recent days, Team GB experienced a lean day on Wednesday by their own high standards.
They are still in third place with 22 golds, but there was disappointment for showjumper Nick Skelton, who missed out on any medals in the individual competition.
The equestrian arena will be the centre of attention once more as members of Britain's successful dressage team go for individual gold.
In Hyde Park, Keri-Anne Payne hopes for a medal in the 10km outdoor swim.
Luke Patience and Stuart Bithell are assured of at least a silver medal in the men's 470 class sailing at Weymouth, while Hannah Mills and Sasia Clark will go for gold in the women's event.
A highlight of the day will come as Usain Bolt takes to the track in the evening in the 200m men's final at the Olympic Stadium.
Bolt sealed his place in Olympic history on Sunday as he became only the second man to defend the 100m title.
Britain's Lawrence Clarke last night admitted he was stunned by his "amazing journey" after finishing fourth in the 110 metre hurdles final.
Clarke set a personal best of 13.31 seconds to reach the final as the eighth fastest qualifier.
And the 22-year-old returned to the track two hours later to finish just outside the medals.
He said: "I can't believe I came fourth in the Olympic Games. I didn't expect to reach the final."
Britain has so far won 22 golds and 48 medals in total - the host nation's best haul since 1908.
