i bike vigorously for a couple hours a day, do some extra running and lift every day. Nutrition i'm still working out, because i have a super fast metabolism. I was looking into maltodextrin and of course plenty of protein. Right now i eat about 10,000 calories a day of mainly healthy food and plan to up that amount for the trip. I am planning for the trip to be in june or july, so i know i will need lots of water; i'm prepared for that plus the extra sets of clothes (good and bad weather). I will stay in motels every couple days and camp out the other days. I can easily handle 100 miles a day for several days in a row and i am increasing my speed each week.
i will give more info later... i'm still sorting out the map, i've looked at a couple, but i plan on making my own map, and avoiding big cities and major roads when possible
