On this day in 2008: Michael Phelps breaks Mark Spitz’s Olympics record

Michael Phelps won his eighth gold medal of the Beijing Olympics on this day in 2008 to break Mark Spitz’s record for victories in a single Games.

Phelps was part of the United States team that won the 4x100m medley relay, meaning he had taken gold in all eight events he had entered.

It was the seventh of his eight golds to come with a world record, the only exception being the 100m butterfly.

Spitz previously held the single-Games record when he swept the board with seven golds at the Munich Olympics in 1972.

Phelps, who had won six Olympic titles at the 2004 Athens Games, would go on to win a further four gold medals in London in 2012.

He then announced his retirement but reversed that decision in 2014 and went on to win five more golds in Rio in 2016, making him the most successful individual at a fourth Games.

When he retired for the second and final time he did so with 28 Olympic medals, 23 of them gold, a record better than 161 nations.
