The Hash House Harriers is an international group of non-competitive social running clubs. Enthusiasts refer to themselves as “hashers” and to the activity as “hashing”. Although the parameters that each chapter sets may differ, in general, a hare sets a trail and is followed by the pack. At the run’s conclusion, hashers typically eat, drink, and socialize. The group typically gets together to humorously note on-trail misbehavior with tongue-in-cheek drinking songs and “down downs”.
