I used to smoke cigarettes while running my yearly 2 mile physical test in the Army. I didn't set any records, but I always finished below the minimum listed time.
Many years ago, there was a half-marathon in Wausau, Wisconsin, where four dumb ex-high school cross country runners decided to stop at every bar along the race's route and drink one beer at each bar. We found out there were A LOT of bars along the route, but we did stop at each one (and surprise a lot of bartenders along the way when we said we needed our beers FAST because we were in a race!). No problem, except that one of us tripped over a parking curb at the 13 mile mark near the finish line and broke his fall with his face. He didn't notice.
And while running with all that freshly consumed liquid in you is no mean feat, he didn't run a mile; he ran four quarter miles with a rest between.
