It might be the only athletic event where there's an official penalty for puking.
We're talking about the beer mile, a running/drinking track competition in which competitors must chug a beer at the starting gun, run a quarter mile and then repeat the process three more times.
The standard rules mandate that the runner — and all four beers — have to cross the finish line together. If you throw up in the middle of the race, you have to run a penalty lap.
The race was invented by a handful of young Canadian runners in 1989, according to a Runner's World article. The idea spread in the North American running community as an under-the-radar race, held mostly by college runners to celebrate the end of the cross-country or track season.
"It was definitely not the kind of thing you'd do in daylight," said Joachim Marjon, a 33-year-old lawyer in Rochester, Minn., who did beer miles when he ran for the University of New Mexico.
In recent years, however, the beer mile has gone mainstream, with highly publicized world championships attracting elite runners and sponsorships from running shoe companies.
Beer miling has even trickled down to the Joe Sixpack running crowd.
In Minnesota alone, there are at least three beer mile events that anyone over 21 could race in this summer. And one of the best beer milers in the country happens to be a Bloomington man who will be traveling to London this weekend to compete in an international championship.
