There is a wide range of exciting sporting action taking place on day five of the London 2012 Olympic Games. Sports Mole has previewed the best bits.
10.30am - Men's coxed eights rowing final at Eton Dorney
Many pundits have suggested that Great Britain are guaranteed at least a silver medal if they perform to their potential.
To achieve gold, however, they must finish ahead of Germany, who have been world champions in the event for the past three years.
11.14am - Men's 200m individual medley heats at the Aquatics Centre
After officially becoming the most successful Olympian of all time last night, Michael Phelps will return to the water this morning.
Phelps and Ryan Lochte, who is also competing, have between them held the world record in this event for the past nine years. With both men seemingly at the peak of their careers, the current record of 1m 54s could be eclipsed yet again.
The semi-finals of the event begin at 8.36pm.
12.30pm - Cycling time trials from Hampton Court
In all, there are 21 gold medals up for grabs today and there is no doubt that Team GB's best chance of breaking their duck is in these two events.
Tour de France winner Bradley Wiggins is the odds-on favourite for the men's race, which begins at 2.15pm. Wiggins's Team Sky teammate Chris Froome has also been tipped to be in contention for a podium finish in the 44km race.
The women's event, which takes place over a distance of 29km, features 2008 silver-medallist Emma Pooley.
4pm - Andy Murray in third-round action
British number one Andy Murray has yet to drop a set in singles competition at London 2012. The Scot's match with Marcos Baghdatis is third up on Centre Court and should begin at around 4pm.
Murray is also scheduled to play again later in the day. He and mixed-doubles partner Laura Robson are last up on Court 18 for their match with Lucie Hradecka and Radek Stepanek of the Czech Republic.
7.40pm - Water Polo: Team GB vs. Australia at the Water Polo Arena
The women of Great Britain and Australia will continue their long-standing sporting rivalry - this time in the pool.
Team GB, who are the rank outsiders in the competition, began their Olympic campaign with a narrow 7-6 defeat to the much-fancied Russian side on Monday.
Australia are heavy favourites to win this match comfortably. However, considering these nations' clear dislike for one another in the sporting arena, this already ultra-physical sport could get even feistier and it is definitely worth watching.
7.45pm - Football: Team GB vs. Uruguay at the Millennium Stadium
Unlike their female counterparts, Stuart Pearce's men have, so far, failed to sparkle during their opening two group games - despite taking four points from two matches.
There will be no room for slip-ups in Cardiff tonight, where a defeat would almost certainly spell early elimination.
GB can also guarantee that pantomime villain Luis Suarez and his side are knocked out of the tournament by claiming three points.
