Thank you everyone. I have a few more days to think about this and do another set of back to back rides. No riding today, I really needed the day off. I can ride tomorrow but then the next day I am tied up all day. After that I can do a string of days of riding.

I am a decent fit on my road bike, with a pro fit a couple of years ago. My last back to back rides was on my Terry which hasn't been fitted to me. I rode it for the wide tires on the gravel. It isn't a drop bar bike, it has sparrow bars I outfitted with bar ends and is comfortable unless the distances are really long. I get hot foot (no clipless on the bike) and generally sore after about 40 miles. I'll try to have my next set of rides on my road bike.

I like Billy's thought about doing 5 or 6 days in a row.

I haven't heard back from the tour organizers yet about pace.
