.... Unless it was a pace line..... good luck with that.

I'd guess 98% of all tourist average less than 100 a day but I'm going to guess it would be closer to 99.5%. It can be done but are you in condition to do it? Even with my 8-12K miles per year riding that includes fast group rides and touring I wouldn't want to average that kind of mileage. Might be possible if I could find three or more equally fit cyclists that I could pace line with day after day.... otherwise... reconsider your mileage.
