Overall. I think that if you have an open mind for such a trip, that only good things can really be said. There is nothing negative that stands out in my mind of any consequence - I am very appreciative of the great time I had and hope to repeat in the future!
To some people it was a challenge and they did fine, we actually added about 15 miles (24 km) /day (but we bike a lot).
I will be recommending it to my bicycling friends.
I appreciate how well the organizers worked together. I didn't have to worry about running out of water, nor about little particulars that might have occurred. It made for a stress-free ride.
