I've done this one twice before, as the August version, and it was always a good race. But yes, it is hilly. I'm sure ukresultsman will be on here soon to tell you more (or just visit ukresults.net).
The goodie bag last August was good - it had a mug, a little money purse-type thing, a little sponge (!) and a Soreen cereal bar.
Not sure why it would be like cross-country though...
