Swimmers around the world took on Katie Ledecky‘s milk-glass challenge since it became a social media sensation, including one of the few U.S. swimmers with more Olympic gold medals.
Mark Spitz, who won seven golds at the 1972 Munich Games, took 10 strokes in an at-home pool while perfectly balancing a glass of what appeared to be water on his head.
“Would’ve been faster with the ‘stache, @markspitzusa, but I still give this 7 out of 7 gold medals,” Ledecky tweeted.
Spitz joined fellow Olympic champions Susie O’Neill of Australia and American Matt Grevers in posting similar videos to what Ledecky first shared Monday.
