Here’s a list of few things that might make the Tough Mudder experience more tolerable. ;)
1) As much of a hassle as it is, I highly recommend wearing a hydration pack. One of the water stations was out of water when we got there. I saw people drinking creek water in desperation (parasites anyone?) and several poor souls getting IV’s from medics. A kind spectator gave me and my teammate a Muscle Milk and an energy gel pack – that saved us! Guess getting stuck in a mud pit with our calf muscles seizing up made him feel sorry for us.
Do not let yourself get dehydrated, and consider bringing some energy gel. Leg cramps due to dehydration toward the end can take you out. After all of that effort, quitting was not an option!
