It was peaceful being away from engine sounds and the crowded areas. Beautiful scenery and most of the time you felt like the only people there. I gave it a 4 (there is no 4.5)because, for me, it was harder than I expected based on reviews. I mean, you are moving your body! I was definitely tired after some of the longer hills and inclines, however, I believe we mistakenly took a harder path. My legs, however, were not taxed and not aching the next day. Bikes ran well. Glad I went. Overall, good experience.
