I'll be there, you don't stand a chance DT.
Route looks interesting, don't know that area too well.
I've just got back from a weekend do organised by work colleagues in the Czech Republic, and it seems I'm in fairly good shape at the moment for the dancing!
10k trail race in the morning, followed by beer (or for some people beer at the drink station halfway), followed by lunch and beer, a snooze, then barbecue and beer, sprint races, dinner and beer, presentations and beer, buffet second dinner and beer, my specialist event of dancing and beer, midnight swim, back to dancing and beer and the Czech version of champagne, then to the bar and beer when the disco finished way to early at 3am, room party once bar closed, with the local spirit as we'd run out of beer.
Get to bed about 6, up at 8 for breakfast to find the boss of the region who had been at the party when I left now eating breakfast with a beer. I need a bit more training to keep up

I think I may need the longer run in the day to keep me out of trouble long enough.
