CYCLING: MEN'S ROAD RACE
- Starts 10am on the Mall
Mark Cavendish is widely thought to be the man who could scoop the first gold medal for Britain in the 2012 Olympic Games.
The cyclist is among the favourites to win the 250-kilometre road race on Saturday's opening day which will feature nine ascents of Surrey's Box Hill and finish on the Mall.
Cavendish is joined in the five-man squad by Tour de France winner Bradley Wiggins, Chris Froome, who was second, David Millar and Ian Stannard, and feels the team could not be stronger.
SWIMMING: MEN'S 400 METRE INDIVIDUAL MEDLEY
- Heats begin at 10am
- Final at 19.30
American swimmer Michael Phelps will begin his campaign to win seven golds at the Aquatics Centre tomorrow.
He will go head-to-head with team-mate Ryan Lochte in the 400 metres individual medley.
Phelps, the most successful Olympian ever with 14 golds to his name, will be hoping to emulate his success in Beijing when he swam and won eight events.
SWIMMING: WOMEN'S 400 METRE INDIVIDUAL MEDLEY
- Heats begin at 11.15am
- Final at 8.05pm
Hannah Miley is a very real contender to secure Britain's first swimming medal at the Aquatics Centre.
She is strongly fancied to add to the medals she has won at world, European and Commonwealth level when she goes in the women's 400m individual medley, which will see the final concluded in the evening.
TENNIS: MEN AND WOMEN'S DOUBLES

Andy Murray will return to SW19 less than a month after his heartbreaking defeat to Roger Federer in the Wimbledon final - and he will be looking for glory in the singles and doubles competitions.
The British number one and his brother Jamie will play their first round match on Saturday against the Austrian pair Jurgen Melzer and Alexander Peya.
Murray will then be back at Wimbledon on Sunday to face Switzerland's Stanislas Wawrinka in an extremely tough first round match.
GYMNASTICS: MEN'S QUALIFICATIONS
- The qualification rounds will begin at 11am and continue throughout the day.
Pommel horse specialist Louis Smith, who ended Britain's 80-year Olympic medal drought in gymnastics four years ago in Beijing with bronze on the apparatus, will begin his bid to try and go two better and scoop gold at this year's Games.
Smith and his Great Britain team-mates Daniel Purvis, Kristian Thomas, Max Whitlock and Sam Oldham will compete in the qualification events tomorrow at the North Greenwich Arena which will either make or break their Olympic Games.
As a team they need to finish in the top eight in order to qualify for the team final, while individual apparatus and all-around final qualifications will also be decided.
ROWING: WOMEN'S PAIR HEATS
- Heats begin at 9.30am

- Great Britain play at 5.15pm
Great Britain will be hoping to build on their 1-0 win over New Zealand on Wednesday when they face their next Group E fixture.
