Here's the flyer for the Larch Hill XC race which I did last year and highly recommend: http://www.commonschool.org/pdfs/Rac...yer%202010.pdf

It's mostly on grass, with hay bales to jump over and lots of mud (at least last year it was muddy). There's food after. There is also a costume contest since it's Halloween weekend...last year the winner was a guy dressed as Lt. Dangle from Reno 911--it was hilarious!!
