Its called Muck Ruckus, an all day slog though slime thats reminiscent of Marine Corps boot camp at Paris Island or Camp Pendelton. Its got to be the nastiest fund raiser I’ve shot over the course of 40 years as a news photojournalist.  On the western reaches of  Wisconsin hill country, hundreds of runners took on the course with all its exhausting challenges.

Muscular sclerosis, a degenerative neurological disease, brought competitors from Wisconsin and Minnesota to the Muck Ruckus challenge to raise money for research toward a cure for the disease.
