Beijing: Michael Phelps swam to a record-breaking eighth gold in a single Games on Sunday to end a stunning week of achievement in the Olympic pool.
The Baltimore Bullet won the 4x100 meter medley relay with Team USA to become the first athlete in Olympic history to win eight gold medals in one edition of the Games.
Phelps has overtaken the previous record of seven Gold medals set by Mark Spitz at the 1972 Munich Olympics.
