Mark Spitz’s Seventh Heaven Immortalised On Olympic Heights

For 36 years, Spitz’s 7 golds in 7 WRs at Munich 1972 was the high bar of all Olympic sport. And when Michael Phelps made it 8, with 7 WRs in 2008, Spitz said: “Bob [Coach Bowman] & Michael... what you did tonight was epic, and it was epic for the whole world to see how great you really are... ”

Today marks the fourth of Michael Phelps' eight 400IM World records, which we paid tribute to on June 29, like this, to mark the day the American set the first and last of his medley masterpiece global standards:

The Day Michael Phelps Set The First & Last Of His Medley Masterpieces 

June 29: on this day, Michael Phelps placed two entries on an epic list of 39 global long-course standards, one in 2003, the other in 2008. The 39 marks the biggest score of ultimate standards by a man in swimming history. It all unfolded 2001 to 2009 and included 8 records set at the Olympic Games, 7 of those set during the 2008 Beijing Olympics. 

Michael Phelps' June 29 records, a day before his birthday (born June 30, 1985), marked the first of his eight 200m medley standards, and the first sub-1:58 in history in 2003; and the last of his eight World records over 400m medley, one that stood between 2008 and the arrival of Léon Marchand (FRA) as the swiftest 400IMer in history, both outstanding all-rounders coached to those heights by the same man, Bob Bowman.
