If you never hashed or you only run urban trails, the word 'shiggy' may be foreign to you. Well, you're right!
...The Hash Is No Exception!
"Shiggy" describes an off-road hashing trail through muck, mud or other wet areas. The Brits and Aussies who ran the first hashes in the 1940s ran the risk of shigellosis...
...from running through swamps. Brushy areas are also "shiggy," which take its root (pun intended) from the Japanese verb ã—ã’ã‚‹ (shigeru), meaning "to grow thick."
