My husband and I have ridden sections of the trail from Portland to Augusta. There is a combination of tree shaded areas and areas in full sun. I would repeat the advice of others, keep hydrated. I learned this the hard way. Last August, we rode from Marthasville to Augusta without any drinks. There was no water fountain at the Augusta stop. We had to walk our bikes up the hills of Augusta in search of a little country store that sold drinks. I bought a backpack the next day and never bike without water. (The bathroom at the Portland stop was very nasty 6/13.)
