I've run Mudder/Spartan races before. The water/mud will make everything stick so your only option is probably the fanny/lumbar pack. Last year I tried to run with a lumbar pack. It was about as uncomfortable as it sounds. Placement on the front interferes with belly crawls and climbing over obstacles. Placement on the back can snag on the barbed wire as well as give you a good dig in the kidneys if you get knocked from behind. Considering the large numbers of participants in close quarters pushing/shoving each other, I wouldn't recommend it. This year I'll be running with clothes only.
