Craig’s blog is a very good guide to the Ben.
Very technical route indeed. Certainly way beyond any of the Stanes for sustained difficulty.
Did it last August on a perfect day. We were 3 1/2 hours to the top with only about a third of it at best being ridable.
The descent was the hardest ride i have ever done in terms of technicality, effort and length. It was brilliant !!
You can ride about 95% of the descent, providing you can manage blacks at trail centres. The only troublsome bits are some of the corners high up where they are very tight and some choke points between rocks.
But don’t let any of that put you off, it’s a blinding day out.
