Following Rose's advice from over at Eat, Drink and Be Meiri, I tested out my intended Mud Run gear last night. She was my inspiration for signing up for this crazy fun run and she suggested that you try on the clothes you plan to wear and stand in the shower to make sure that once wet, your clothes don't fall off or get so loaded down with mud that you can't actually run.
Thanks to The Pilot for catching this gem. Yes, I always shower with my clothes on and with a surprised look on my face. Soaking wet and nothing fell off! I think this is what I'm going to go with!
