running through smoke
more trail mud (with hidden deep spots)
"sucking mud" at the finish line (or where shoes are left behind)
Tips: Hubs was happy with his decision to wear cargo shorts for the Mudder. In his pocket (that snapped shut), he had a pair of goggles, for the swimming portions, and a waterproof flashlight, for the closed tunnels he had heard might be really dark. He also wore these gloves that I bought him for yard work and said they did a great job protecting his hands.
