James Nielsen succeeded in setting the new world record for the Beer Mile with a time of four minutes and 57 seconds this past weekend. The Beer Mile requires runners to consume four beers at specific intervals while running a mile. In short, chug a beer then run a lap. Then do it again. And again and again.

The Official Beer Mile Rules are listed on the website. When asked “What makes these rules so special and why is BeerMile.com the authority?” the website’s answer reads:

“They’re not, and Beermile.com is not an authority. This site is just a centralized place to share beer mile thoughts and stories, and creating a consistent list makes competition more fun. Any variation of these rules is accepted, just not as “official” by Beermile.com. Most of these rules are widely accepted by beer miling communities and you will be hard-pressed to find severe deviation.”

Clearly, it’s a very strict organization.

Nielsen had his wife film the new world record, which was the first sub-five-minute Beer Mile in history. The previous record was set by Jim Finlayson in 2007 with a time of 5:09. As for Walker’s thoughts upon completing the challenge: “That is really painful. Holy shit.”
