Yeah, as John says, there's a stile within a few hundred yards of the start (can't rememeber the exact distance), you'll want to really slam on the gas from the start.
In good weather you shouldn't need to know much more really. Oh, make sure your shoes are tied on well, shoes always seem to get lost in this race (bogs should be easier than usual but I wouldn't bank on it).
The first half to the trig point is a nearly obvious route along the Penine Way, then it's fully marked from the trig point at the top (in bad weather this can be very difficult to follow).
Good luck Matt, I'll have a couple of quid on you.
