Nice to see a few of you guys still there when I arrived. There were a couple of moments when I found myself wishing I'd opted for the road version but, on the whole, I had fun 
Walked the first few hundred yards of the cross bike route after racking my trusty, but little used MTB and almost withdrew then and there! Chatting to others in transition area who'd ridden the course yesterday didn't do a lot to boost my confidence either, tales of extreme mud jamming up gears/wheels etc. Eventually time came to put on wetsuit only to discover that it's developed several splits at assorted seams since I last used it a couple of weeks ago 
Swim - not too bad; followed feet most of the way to the turn and most of the way back slightly out to one side. Not sure why my ability to swim in a straight(ish) line always deserts me on the return leg of any ow swim. Out of the water in about 16:27, couple of minutes gentle meander up to transition.
Wasted much time faffing in T1 as usual but did have the excuse that, being too much of a wuss to ride the MTB clipless, I was pedalling in my trail shoes so had to tie laces.
Bike - that first bit, that I'd walked, actually turned out to be one of the easier bits. First mile or so was pretty straight forward single track and across fields. Then it got interesting for the next couple of miles. Skinned my shin trying to negotiate the first of many ditches; then it got muddy. Really muddy, just one stage short of mud soup. Walked a short stretch which involved ankle deep mud and a slight step up onto a bridge. Collected enough mud to negate the effect of the nobbles on my tyres before slithering out of the woods and onto a field where the relatively recently cut grass stuck beautifully to the mud till it looked like my wheels and gears were made of straw! Stopped briefly to try to clear some of the gunk away from the gears with some success but shouldn't have bothered cos I collected a fresh lot of mud and grass shortly thereafter. Checked the watch and was a bit horrified to see it'd taken me 40mins to do about 3 miles so not even half way! Ho hum, nothing to do but keep plodding on. Richard Stannard flew past making it look easy - and he was doing the standard which started 20mins after the sprint. Fortunately the course then got relatively easier, mostly cos it was a bit drier. Enjoyed a flypast by the Red Arrows. Then suddenly I was heading towards transition. The advertised 9.5 miles was actually only just over 6 miles. Phew!
Run - more of a plod really at a steady 5:1 plod/walk - except for the uphill slog shortly before the steps up onto the Downslink. Mr Stannard sped passed again as I headed for home and for a brief moment I thought he was on his second run lap and therefore going to finish before me.
All in all, it was fun and I have this odd feeling that I'd really like to do a bit more mountain biking so I can go back and ride the course properly next year
