When someone runs (or stumbles) across the highway, disregarding any and all traffic, instead of using a crosswalk.
Popularized by a viral video of an oblivious woman in Rutland Vermont walking across Route 7 into the side of a truck.
âJesus, that moron almost got hit doing the Rutland Run to get to Dunkin Donuts!â
âDamn I really donât feel like going to the crosswalk, I think Iâm just gonna Rutland Run itâ
