Hash House Bikers (also known as bike hashers, or bashers) is an international group of non-competitive bicycling, social, and drinking clubs referred to as chapters or kennels.
Walter Rye, President of Thames Hare and Hounds, likely alluded to it in 1887, not long after introduction of the safety bicycle: "Another feature which has tended to lower the sport, is the ridiculous number of prizes given in steeplechases, and the 'pewters' and medals presented to the first men in, or first bicyclist in, and so on, in ordinary runs.
"[1] Singapore Bike Hash has solid claim to be the oldest running bike hash chapter or kennel in the world, having started in July 1989 and extant today.
Bangkok Hash House Bikers is not far behind being formed in 1992 and attracting strong contingent every month.
[2] Don Burlinson, aka Missing Link, had an "ah-ha" moment and decided to form a separate bike hash kennel.
