We started at rowardenan and then just went straight up. There is about a mile stretch of open stuff (shown in the photo with teh guy in red) but the very top is pretty technical and switchbacky, then it opens up but is still rocky but very fast. After the smoother bit it roughens up again then gets steep with some fairly tight switchbacks before a fairly steady singletrack rocky wind back.
Ollie's on an RM slayer sprayed in the nastiest shade of sparkly pink I've ever seen. We looked very colourful though- graham's yellow NS, my lime green Norco, ollie's pink slayer, huw's red orange. Like someone had been sick on a pile of bikes.
