Some European dates for 2016:

11-12 June, Retroronde van Vlaanderen, Oudenaarde, Belgium
18-19 June. Anjou Vélo Vintage, Saumur, France.
28 September - 2 October: l'Eroica, Gailole in Chianti, Italy

Mrs non-fixie and I have already booked a room in Oudenaarde , but we'll have to give the other two a miss in '16, I'm afraid.
