My favourite Russian audax club, Balticstar, has a very interesting 1200 next year:
http://baltic1200.ru/Starting in Kaliningrad, passing through the three Baltic countries Lithuania, Latvia and Estonia and finally re entering Russia for a finish just south of St. Petersburg.
I'm strongly tempted to join, especially since I know a lot of the area which is on the menu, and this is really good cycling territory. Just rolling enough to keep it interesting, enough amenities and nice scenery.
Anyone else interested?
