Shilo, I rode to school my junior year, from Boston to Detroit. Very different from your ride. Much longer (800 miles) and far more options for stops/food/water/people. I rode and camped 5 days, stopped at a motel in Niagra Falls to shower and wash, then rode two hard days into the wind to Windsor Ontario.
My advice is to make your first day not so long. I find that I am better the second day and if I have done my homework (enough riding and good prep) by day three I am rolling and the miles come easy.
You will never regret this.
