Longer block tournaments will load carbs night before and low sugar fiber loading morning of or meal replacement shake a few hours before. During I like a little alcohol (most tournaments its not allowed) but more of a tension releiver or nerve soother. Protein bars or meal replacement just after completion as helps muscles replentish what they lost and makes quicker recovery. Bar food at the local house, mean soup( could have anything in it and usually has lots of anything)and the homemade hot sauce on a hot dog before leaving.
