The first-ever Flotrack Beer Mile World Championships were held yesterday in Austin, Texas, with participants chugging a 12-ouncer before each quarter-mile lap. Anyone who tossed their cookies had to keep running. It may sound like a crazy college party, and the Beer Mile indeed harks back to campus hijinks. But real competitors — including Lance Armstrong, who bowed out of last month’s qualifier — train hard to drain their Buds and finish first. The world record is a sobering 4:57 mile.
