A reindeer can run at speeds of up to 48 mph. A grandma walking home from someone’s house Christmas Eve, or any other day, averages about 3 mph. If both the reindeer and grandma were traveling in the same direction and along the same path, the grandma indeed and unfortunately would get run over by the reindeer.
Even Olympic gold-medal-winning sprinter Elaine Thompson, who’s capable of about 21 mph over 100 meters, would have hoof prints.
