Twitter and other social media websites have made the competitors of these Olympics the most accessible ever with many of the tweeting their daily activities.
Here are a few Twitter accounts from some of the world's top athletes worth following:
Jamaican sprinter Usain Bolt (@usainbolt), who holds the record in the 100 metres, posts regularly on his verified account.
His Twitter biography humbly suggests that he is "The most naturally gifted athlete the world has ever seen," and Bolt's tweets reflect his energetic and charismatic personality.
"I know some ppl your name will be on the list," tweeted Bolt to Piers Morgan (@PiersMorgan) on July 27 after the CNN interviewer posted "I want to be at the Jamaica #Olympics after-party," on his Twitter account.
American swimmer Missy Franklin (@FranklinMissy) has emerged as a star at these Games. The 17-year-old posts on Twitter regularly, retweeting messages from fans and fellow athletes as well as her own positive messages.
"I could not be prouder of my team and my relay tonight! I am so proud to be an American! Your support means the world to us! Thank you!" said Franklin on Wednesday.
Sir Chris Hoy (@chrishoy) is one of the most successful Olympic athletes in British history and, naturally, is one of the most popular athletes at the London Games.
As a four-time Olympic cycling champion, Hoy was a logical choice to be Britain's flag bearer at the opening ceremonies. It also made him one of the most prominent voices supporting the home country's athletes and de facto spokesman for the British athletes.
"Losing track of all the medals the team is winning, congrats to everyone so far. 4th on the medal table as I type this..." Hoy said of Team GB's podium finishes on Friday, adding the hashtag #nice.
Novak Djokovic (@DjokerNole) was already well known before the Olympics as one of the world's best tennis players, but he's representing Serbia for the second time at the Olympics.
"Hope It wasn't too bad for ur nerves to watch me play today? It wasn't easy! :) Wish me luck!" tweeted Djokovic after his 6-1, 7-5 quarter-final win over France's Jo-Wilfried Tsonga on Thursday.
He added a photo of himself giving a double thumbs up while wearing a Serbian Olympic team tracksuit.
