I've been discussing bike trips with Mrs R over the last couple of days and her reaction to DZ's itinerary was:
(a) to check that this was in addition to, rather than instead of, the ride to Paris that she'd like to do next Summer; and
(b) to say that it sounds like an excellent idea, not least because she would then not feel guilty about going on a Baltic tour with her choir in May.
I'd be interested to know what options for accommodation and long-distance transport start to emerge. I'd be keen to be able to ride my own bike on such a trip, and could cope with camping, particularly if there's a support van of some sort.
