Friday brought to a close the first full week of Olympics 2012, and with it came another set of incredible displays of record breaking.
Roger Federer (Switzerland) and Juan Martin Del Potro's (Argentina) exhausting epic tennis semi-final was the longest Olympic tennis match ever played out, lasting a grueling 4 hours and 26 minutes.
Federer went on to win the match 3-6, 7-6, 19-17, setting up a showdown for gold with Great Britain's Andy Murray.
Swimming machine Michael Phelps (USA) extended his records for the most career total Olympics medals to an incredible 21 and most career total Olympics gold medals to 17, following another victory, this time in the men's 100m butterfly final.
Elsewhere in the aquatics centre, Missy Franklin (USA) notched up the fastest 200m backstroke long course (female) world record with a time of 2 minutes and 4.06 sec.
Meanwhile, USA teenager Katie Ledecky powered her way to victory to become the youngest winner of the Olympic 800m freestyle (female) at the age of jut 15 years and 139 days, coming home in a time of 8 minutes and 14.63 seconds.
The day's action in the velodrome saw a new world record set for the fastest track cycling team pursuit (male) in the event's final by Ed Clancy, Geraint Thomas, Peter Kennaugh and Steven Burke for Great Britain, with the quartet racing home in an amazing time of 3 minutes and 51.659 seconds.
Elsewhere, Great Britain's Dani King, Laura Trott and Joanna Roswell shattered the record for the fastest track cycling team pursuit (female), shattering the previous best in a time of 3 minutes and 15.669 seconds.
Finally, Sergei Martynov of Belarus set a new world's best in the men's 50-meter rifle prone winning the gold medal he had been looking for at six Olympics.
Martynov became the second shooter in Olympic history to score the maximum 600 points in qualification and finished with a world record total of 705.5 points, beating the 12-year-old mark from Germany's Christian Klees by 0.7.
