Id keep the road work to a minimum 2 days before, and no grinding it out the day before. just a light warm up, maybe hit the mitts. Make sure you get plenty of rest the night before, and eat a good energy meal for dinner the night before, drink a little milk as well if you can. Lots of energy cals in milk. Hydrate well with water the day of the fight, and other than that, just try to stay relaxed and rested so you put yourself in the best position to win. Good luck !
