DAY ONE IN A NUTSHELL
Shocks - Great Britain's cycling road race 'Dream Team' failed to propel Mark Cavendish into the medals. The five-man home team, including Tour de France winner Bradley Wiggins, failed to reel in a large breakaway group, leaving Kazakhstan's Alexandr Vinokurov to take gold on The Mall.
An even bigger surprise came in the pool where Michael Phelps also failed to medal in the men's 400m Individual Medley, as Ryan Lochte won the American swimmers; first big duel. Phelps had won the IM at each of the last two Olympics.
LEADING BRITS IN ACTION
Helen Glover and Heather Stanning set a Games record in their heat to confirm their status as favourites to win Britain's first Olympic gold medal for a women's crew.
Britain's male gymnasts qualified in third place for their first final since 1924
Hannah Miley's dreams of gold were shattered as she finished fifth behind China's Ye Shiwen in the women's 400m IM.
Great Britain's women's football team booked their place in the quarter-finals with a 3-0 win over Cameroon, their second of the tournament.
Andy and Jamie Murray crashed out of the tennis men's doubles in the first round, losing to Austrians Juergen Melzer and Alexander Peya.
Elena Baltacha breezed into the second round of the women's singles tennis, but Anne Keothavong fell to Caroline Wozniacki in three sets.
Mary King produced a solid dressage to start to her eventing campaign. She lies third, while Nicola Wilson is 16th.
Boxer Anthony Ogogo defeated Junior Castillo 13-6 to progress to the second round of the middleweight competition.
A STAR IS BORN
Ye Shiwen - The Chinese swimmer produced an astonishing world record-breaking performance to win the women's 400m Individual Medley. Ye knocked five seconds off her previous best to accelerate clear of the USA's Elizabeth Beisel. At 16, she could dominate for years.
Italy - Off to a flier with five medals, including two golds. The undoubted highlight came in the fencing, where Italians stood on all three podium steps in the women's Individual Foil. Our tip Valentina Vezzali took bronze behind Elisa Di Francisca and Arianna Errigo. They are second in the medal table.
Great Britain - Let's not kid ourselves. Expectations were sky-high going into the opening day of full competition - but Britain ended without a medal. The cyclists' failure was a major shock to the system. Five more genuine medal hopes go on Sunday, including swimmer Rebecca Adlington.
Kieran Behan - The Irish gymnast was eliminated from the vault and floor events, but his mere presence in London is one of the great Olympic feel-good stories. Behan developed a tumour in his leg aged 10, and was told he would never walk again. He emerged from his wheelchair, only to suffer a serious head injury falling from a high bar two years later. Again, he defied doctors' fears he would never walk again. His progress was again derailed by a major knee injury, but on Saturday the 23-year-old fulfilled his Olympic dream.
QUICK OUT OF THE BLOCKS
Yi Siling of China took the honour of claiming the first gold medal of the London Olympics when she won the women's 10 metre air rifle.
QUOTE OF THE DAY
"It seems most teams are happy not to win as long as we don't win. There are 70 guys in our group (who missed out as well). Nobody wants to help us. The Australians rode negatively. I'd like to say that's how it goes, but it's disappointing." Mark Cavendish
