1338: Back to the road cycling and Australia's veteran Stuart O'Grady, a sprint specialist and three-time Tour de France stage winner, is lurking menacingly at the top of the breakaway group, which has seen its lead whittled down to just under two minutes. David Millar, GB's team captain, is upping the tempo and the hosts are producing a text-book ride to ensure the "Manx Missile" Mark Cavendish is in prime position for the mother of all sprint finishes in the final kilometer.
1404: While our Ben goes all green fingered (or purple petalled), we're under 80km to go in the men's cycling road race and the breakaway group, which had a six-minute lead at one stage, has been swallowed up by the peloton at Box Hill. Britain's first ever Tour de France winner Bradley Wiggins leads the GB train with Mark Cavendish nestled comfortably alongside David Millar and Ian Stannard. So far so good for the hosts.
1435: Back to the cycling with under 90 minutes or so to go until the glorious road race finish on The Mall. So who are the main riders in the mixer for gold? We have the Manx Missile, the Gorilla and the Terminator. They may sound like wrestlers but GB's Mark Cavendish, Germany's Andre Greipel and Slovakia's Peter Sagan are among the best sprinters on the planet. However, much will depend on the gruelling donkey work done by their team.
1440: That Martha, is a very good/cruel shout. Better news for Tipsarevic is he's through to the next round of the men's singles after a 6-3 6-4 win over Argentina's David Nalbandian, he of the famous accidental referee-kicking tantrum at Queen's Club.
1454: Over at the more quaint and tranquil surroundings of SW19, home of the All England Lawn Tennis and Croquet Club, five-time women's singles Wimbledon champion (and this year's winner) Serena Williams is 5-2 up in the first set against Serbia's Jelena Jankovic. There's an important figure watching from the stands as first lady Michelle Obama nods in approval.
1504: Staying at Wimbledon, men's sixth seed and ex-Wimbledon finallist Tomas Berdych is the biggest casualty to tumble out of round one so far, going down to a 6-4 6-4 defeat by the relatively unknown Steve Darcis of Belgium. Darcis' compatriot Kim Clijsters is also through to the safety of the next round following a 6-1 6-4 win over Italy's Roberta Vinci.
1515: The men's cycling road race is building up for a thunderous climax with the USA's Tejay van Garderen at the head of a chasing pack, where Spain lurk menacingly. Interestingly, Bernhard Eisel, a Team Sky rider, seems to be assisting his British team-mates. The Austrian is the man who sets up Mark Cavendish for his sprint finishes, acting as a guide before unleashing the Manx Missile's astonishing final 500m speed. And it looks like GB's Chris Froome, who finished second on the Tour de France behind Bradley Wiggins, is cooked. Under 30km to go...
1518: Touche Danny. Some sad news to report: Albanian weightlifter Hysen Pulaku has become the first athlete to be ejected from the Olympic Games for failing a drug test. The 19-year-old tested positive for the steroid stanozolol.
1525: With just over 20 kilometers to go as the riders hit the verdant Richmond Park in south west London, Britain's Mark Cavendish is over 50 seconds behind a breakaway group in the men's cycling road race. After looking comfortable about 30 minutes ago, they've been suckered by an intelligent counter-attack by Switzerland, lead by Olympic time trial champion Fabian Cancellara. Bradley Wiggins and David Millar are working flat out for Cavendish, but can they close the gap when it matters? Tense finish in store...
1533: To all of our bleary-eyed American readers waking up after a show-stopping opening ceremony, you join us at a dramatic moment in the men's road race as Olympic time trial champion Fabian Cancellara locks his back wheel going around a bend and smashes into the barriers with about 10km to go until the finish line on The Mall. The Swiss had been among the front riders in a breakaway pack. GB's "Dream Team" are pedalling for all their worth to get world road race champion Mark Cavendish in a position to attack in the final stretch.
1541: Kazakhstan's Alexander Vinokourov and Columbia's Rigoberto Uran are the surprise leaders with about 5km to go - and it looks like the GB medal quest looks to be over as they trail the leaders by 40 seconds or so. The leading duo's gap is about five seconds.
1544: Vinokourov, clad in an eye-catching/eye-watering magenta suit, weaves through the Knightsbridge streets as they towards The Mall, where the finishing line awaits. The Kazakh, who won silver in Sydney 12 years ago, looks strong.
1545: So who's the better sprinter - Vinokourov or Uran? We're about to find out very shortly with the closing stages to come. To win gold it's...
1556: The guile and experience of Vinokourov hits Uran as the Colombian glances over his left shoulder looking for the Kazakh with about 500m to go until the finish line. And the 38-year-old Team Astana rider beams an almighty smile as he adds possibly his most impressive title to date to his illustrious list of accolades. He's been close to retiring several times over the past few years. Great silver for Uran, who would've predicted that? The bronze medal to follow...
1559: And Norway's Alexander Kristoff held off a desperate charge on the finish line to nose the bronze medal behind Vinokourov and Uran. Unfortunately, Great British Attack wasn't quite executed as planned with world road race champion Mark Cavendish left stranded without a lead-out man for the finish. The Isle of Man sprinter and 23-time Tour de France stage winner finishes 11th. All domestic hopes now turn to the women's road race on Sunday where Nicole Cooke defends her Olympic title.
1610: Jin Jong-oh wins the second gold medal at the Royal Artillery Barracks, home of Olympic shooting in the capital, as he holds off Italy's Luca Tesconi. It's South Korea's first gold with another likely to follow in the men's team archery event at Lord's. The country is still smarting from the disqualification of Olympic 400m freestyle champion Park Tae-hwan this morning.
1629: Back over to south-west London and the perfectly manicured lawns at Wimbledon and seven-time Wimbledon champion Roger Federer finds himself 6-5 down in the second set against Colombian Alejandro Falla in the first round. The Swiss glides across the court with his customary lucidity but an unforced forehand error allows his left-handed opponent to level the match at 1-1. Remember, the men play best of three. Potential shock alert.
1653: Doesn't much look like she's celebrating, does it? In fact, when I first saw the photo, I feared the very worst... Right, get your thinking caps on, because it's time for the big question of Day One...
