For those of you that aspire to a ride like this- Don't bother. The rider, or one of them is Hans Rey. That name should be said with reverence as the worlds best Trial- trick and Technical mountain bike rider in the world. And We do have a couple of good trials riders in the UK so rate him highly.
And NO- I do not even want to ride this sort of trail.
