As Dave explains in full on his blog,
"Right now I am preparing for a very special project I am trying on Ben Nevis and I already completed one or two of my training climbs which I saw as benchmarks for a prerequisite physical level. But it's obviously just as important to spend time doing some psychological skills training for a climb where the seriousness of a fall could not be higher. For this climb I need to be able to climb 8c+/9a in an unprotected position. So I must have great confidence in my ability to make good decisions in a situation close to my physical limit but under a lot of psychological pressure."
