I entered in my first GTEC Dirt Bike round on the weekend of the 28th of July. It was Round 4 was a 3 hour Pony XXXpress.
For those not in the know, the Pony XXXpress bit meant that after every lap, you had to shut off the bike, push it about 20 metres, and then take a clothes peg off your bike, and put it on your race partners bike. Your race partner then roosts off into the distance for a time, before coming back, pushing, and putting the peg onto your bike, at which time you go roosting off, and so on.
A few days before the event, I thought that things were shaping up nicely, with rain a few days before, the track should be just damp, with lots of grip, and no dust.
Unfortunately, the rain started again on the saturday night, and was heavy for the whole night. It was raining almost all the way as we drove to the track, and I couldn't help but wonder just how wet it would be.
When we got there it became clear. The track was in a paddock which had a few swampy type holes in it, and indeed, the track went right through a couple of these swamp holes.
Of course, normally these would be just average mud holes, but the overnight rain had left water on the surface in many spots, and of course, the dirt underneath was already mud, let alone what it would become after a few bikes made their way through.
Anyway, it was time for the sight lap. Off went the first bikes, then off we went after them. Stalling the WR on the start line on the non competitive lap may have been a little embarassing, but at least it got that problem out of the way early, not to happen again 
One the first corner, when the front end nearly washed out, I thought to myself "dang, it is slippery". After the front and rear wanted to wash & swap & generally go anywhere they felt like for the next 20 corners, I realised just HOW wet it really was.
By this time, I was getting a little apprehensive, and when I got back to the pits, I'll admit to being almost ready to pull out there and then.
However, since this was a pony xxxpress, and pulling out would disadvantage my teammate, and I definitely did need the practise in mud, I decided that it was worth giving it a go.
Dale, who I was partnering with started the event. He had a KTM 380, which had to be quite a handful in the muddy conditions, but when he came around with the peg after the first lap, he looked to be quite comfortable.
He "pegged" me, and away I went. Second gear start, third gear, just into fourth (wow. lots of wheelspin), and braking for the first corner. Down to second, and crack it open again, and more wheelspin. Hmmm. after a few corners, it became obvious that 3rd gear was the go, no need for clutch or anything, a slight twist of the wrist, and the back end was stepping out all over the place.
On the longest straight, when I could just get into top gear, the rear was spinning all the way until I clicked it into 5th, and then it only didnt spin cause the corner was coming, and I was almost immediately on the brakes.
Hmmm. maybe the standard Australian WR250F tires arent' that good for mud? Must check that on the 'net eh
We continued swapping our peg for a few laps, and the track actually started to berm up in the very driest places, making things a little nicer once you got out of the mud.
However, with the good comes the bad, and after the second lap, my left hand grip decided that it didn't like sticking to the bars at all, and started rotating freely. My own fault I guess, as I hadn't wired the grips on. A couple of zip ties around it at the next pit stop got it secure enough to continue, although still not 100%.
Ruts started to form. Not your normal ruts, but ruts so deep that if you get in them, the bike stops dead. Then you've got to physically lift the thing out, just to get going again. Luckily I managed to avoid these, as I spotted them forming, but quite a few bikes got stuck in the.
Ruts straight through the water covered sections at all angles, which one to take? argh. Crack it open, sit back and hang on was the only way.
With gun riders roosting the thick, vegetable soup like mud all over each other, and anybody else handy, all that was needed was some bikini clad mud wrestlers, and the scene would have been complete. Although I think the racing might have stopped quickly if the wrestlers turned up.
Tree roots became exposed underneath the glopping, glue like mud so that when crawling along with the bike in 3rd roosting like crazy, and you hit a root, the beat gets traction and stalls (where are those e-start wr's ?), or wheelies like mad.
Good clean dirty fun. I think.
At one point, my front wheel got in exactly the rut I wanted, and the back wheel was not. It was a recipe for disaster, and a face plant followed as to be expected 
This took some of the fun out of it of course. However, that was the only get off for the day for me, despite a start! area that claimed at least two bikes & riders towards the end it was that sloppy!
Well, the event went for three hours, and towards the end, we were certainly looking for that finish flag to come out. I didn't go out to do the last lap with a couple of minutes to go, as the conditions had just got so bad that in a couple of places it was a real stuggle just to stay upright. Unfortunately, I think this cost us a lap in the final tally ;-/
We ended up getting 18 laps in the event, with the leaders getting 24. I dont think thats too bad for a guy much more used to riding in sand that has been thrust into mud for a day!
