Ah, good. 49 in one sitting would be a bit much... Not sure where your oysters were from, but if you're in northern France again, apparently ones from Cancale near St Malo are amazing. I don't eat oysters, but hubby was in heaven. Also ones from Ile de Re were very good.
Back to bikes.... We were not going that fast. I'm not a super fast rider anyway, but pushing bike that's probably about 40 lbs or so, and about same amount of luggage didn't make us fly down those roads, let me tell you. I'm not really all that interested in speed when I tour, but it's nice to actually get to your destination
If you have any questions about NWTs ask away.
