I hear this year they will have colored pencils and paper at the start so you can draw your own map, Oh and a pen to write down the clues and, of course, clear tape to laminate it to your arm. ;)
Possum Trotters are so tough we don't bother with maps. We just run from control to control on instinct... and a high-quality list of clues.
Make sure to practice eating pizza flavored Gu in case there is a mandatory pizza-flavored-Gu-checkpoint.
The other thing you need to be ready for is white squirrels. You never know when you're going to meet one of them in the forest and need to have a plan for dealing with that.
I will squirt pizza-Gu in the eyes of the white squirrels and then run away.
