Yes, i did it with one of the Pete’s in that link- he was the brother in law of a good friend and wrote the article that was in issue 36 of stw. Pete died a few years ago but they were just about the best weeks of riding I’ve done.
The route itself isn’t the most technical, a few corners might trouble you on the first descent. Some exposure but no more than the rest of the riding in the area. The short climb will probably feel tough on tired legs but you get a great view at the top. The second descent is harder than the first, one corner in particular (pictured in that article) used to be hard but was a little washed out when i was last there (2008 i think).
It all depends on your group and how competent they are. It’s big mountain riding far removed from the safety of trail centres so you have to look after yourself. On that route one of my riding pals dropped his front wheel,[*] smashed up his face and broke his wrist. Despite being only 10 minutes from the top it took an hour to get him back to the car and down to the hospital.
