Giant on the move
Michael Phelps made light of goggle trouble to claim his fourth gold medal of the Games and then helped his American team win the 4 x 100 m freestyle and make it five wins from five, in fact five world records from five, at these Games.
He now has 11 Olympic gold medals, which puts clear blue water between him and four athletes who have won nine.
He is still on course to break the old record of seven golds at one Games, held by Mark Spitz, after what were two more breathtaking swims on Wednesday.
Victory in the butterfly came despite the fact that goggle trouble was making it difficult for him to see.
