Possible '222 Challenge' runs??

The first official run of the '222 Challenge' will be the Hannover Nachtlauf on the 17th September 2010. Other runs under consideration for the challenge are ... Oct - Dresden half-marathon, Nov - Braunschweig 10km/half-marathon, Dec - Machsee Run 6km, Winsen Aller Silvesterlauf 10km, March - Celle Wasa Lauf 10km, April - Prague half-marathon, Berlin half-marathon, May - Berlin BIG 25, Hannover half-marathon, June - Hamburg half-marathon, Uelzen 10km. Definitely not on the itinerary for this challenge are the Midnight Sun half-marathon (still paying for this year's run!) and the Funf Seen Lauf 15km in Schwerin, unless the temperature is significantly below this year's 35 degrees!! Anyone who knows any other great runs in Northern German or further afield (within economic reason) please leave a comment!
