“Peter Croft once explained the feeling you get from free soloing as a heightened type of perception. A little edge that you need to stand on looks huge—everything comes into high relief. That’s just what happens to your body and your mind when you’re focused intensely on the feedback you’re getting from the environment and there are no other distractions. You become an instinctive animal rather than a person trying to do a hard climb, and that perception doesn’t immediately go away when you get to the top. It dulls over time, but for a while it feels like you almost have super senses. Everything is more intense—the sounds of the swifts flying around or the colors of the sun going down. A lot of times I don’t want to go down, I don’t want it to end.”
