On the Camelfarm side of the valley Utopia is a nice long fun run that is blue with some avoidable black obstacles.
On the Jorgensen side of the valley Augustus Pablo, Loose Lips and Downward Dog (I think) are blue or blue-black and good fun
Ta, I was hoping to print out the trail map before I went yesterday but our stupid computer for some reason won't print anything from the internet and I couldn't download it to a printable format.
I didn't quite make it as far north as Utopia (ran out of time so came back from the powerline trail along the Bibbulmun Track) and didn't ride anything west Schipp Rd at the bottom of the valley - although I did see a couple of tracks dropping into it. Can't see Downward Dog on the map although there are two others with dog in the name.
I'm fairly sure the one I rode out of the valley (the first time) was a downhill track because I had to keep going around obstacles and a couple I had to get off and go up over the rocks. I think it was Wild Boar and later I went down Drift Pig. They're marked as the same track lower down and that's the one with the scary rock surface to ride down.
Ridgeways V2 was the one I rode down that ended abruptly at the bottom, just next to the creek. If it'd been winter, I wouldn't have been able to cross it.
There were a couple of others that aren't on the Trailforks database.
I'll map the whole thing eventually and see if it's usable but I dare say many of the downhills/uphills won't be for a MTBO event, given how many DNFs we had at Banyowla last week! Would be nice to have the contours for that side too (I do have them but I have issues with them at the moment, namely that they're 2m contours).
Yeah it would be hard work for mtbo lots of climb and one way tracks.
