Sixty years ago, Sir Roger Bannister showed that barriers were made to be broken, as the Englishman became the first man ever to run under 4 minutes for the mile with his historic 3:59.4 clocking. On Sunday, James Nielsen of California took down another mark that was previously thought to be unattainable, that of dipping under 5 minutes for the beer mile, which involves drinking 4 beers while running four laps of the track. Watch as Nielson clocks 4:57 to become the first person known to break 5:00 in this unsanctioned event. The previous “official” record, according to BeerMile.com, was the 5:04.9 set by Australian Josh “Harry” Harris in 2013. Nick Symmonds, a silver medalist in the 800m at the 2013 IAAF World Championships, holds the U.S. record for the beer mile with a 5:15.0.

“That was really painful,” said Neilsen, CEO of the nonprofit California Runners.
