Mo Farah will be aiming for a second gold of the London Games on the last day of action inside the Olympic Stadium.
After winning the 10,000m title in stunning fashion, the 29-year-old could become Britain's greatest track and field athlete when he competes in the 5,000m.
Usain Bolt will also be going for his third gold of the Games as the world's fastest man joins Jamaica for the 4x100m relay final.
Britain looks set to boost its best medal haul in more than 100 years as Farah, two boxers and a kayaker aim for the top step of the podium.
Victories in the ring mean Luke Campbell and Fred Evans have the chance to go for gold today, with Britain guaranteed at least two more silvers.
Campbell, 24, from Hull, will take on his family friend John Joe Nevin, of Ireland, as he bids to fulfil his lifelong ambition of winning an Olympic title.
"It's all about the gold medal for me now," Campbell said.
"But I'm proud of what I've done so far and I'm happy to make my family proud and my little lad and my home town of Hull. The support I have received from home and in the arena has been amazing."
Welshman Fred Evans will also hope to continue his magnificent run in the welterweight division.
Another boxer, Anthony Joshua, beat Kazakhstan's Ivan Dychko in his semi-final bout late last night to secure his place in Sunday's final.
Ed McKeever also goes for gold in the kayak sprint after storming through his heats in the fastest time of the day and then winning his semi-final in what turned out to be a formality at Eton Dorney.
Nick Woodbridge will also be hoping to challenge for a medal in the notoriously unpredictable modern pentathlon after winning bronze at last year's Olympic test event.
Diver Tom Daley survived a major scare as he left it until his final dive last night to nervously progress past the first round of the men's 10m platform.
The 18-year-old former world champion produced one of the worst displays of his decorated young career before narrowly sneaking through to this morning's semi-final.
After today's events, the Olympic Stadium will shut its doors to the public to prepare for the closing ceremony on Sunday evening, which is due to be watched by a worldwide audience of around four billion people.
Games chairman Lord Coe described the closing ceremony as an "after-show party".
"It's not anything desperately profound. It's not the opening ceremony but I think it will be great. It's basically a tribute to British music over the last few decades. It's fun."
Artistic director Kim Gavin has already said it will be "an elegant mash-up of British music" including anything from Adele to Elgar.
