Right, my heads in this now. Just finished the Brecon Beacons 10 peaks last weekend, one more 20 mile road run to go and I reckon I'll be set for this one. I haven't the time to recce the route so I'm hoping nav' is fairly easy on the day.
Obstacles; how about a bloody huge mountains, wading through rivers and leaping over gates. It's probably only going to cost you £4 to enter, you won't get a medal, you won't get a t-shirt, you will get your legs ripped off by some 60 year olds that can walk faster than you'll ever run, you might get a free pint, toughmudder hipsters definitely won't understand.
