I harbor similar feelings toward scrambling as I do to skateboarding. While the physical engagement is different when scrambling, I enter a similar state of mind to when I am cruising fast, downhill on the board. Swiftly working my way up the First Flatiron, my whole body is engaged. I know every hold, hand, and foot placement, allowing me to make abstraction of the route, to move freely up the rock, untethered. The easy climbing lets me push myself anaerobically, while the exposure keeps the mind sharp. On the board, my focus is turned downhill to maintain balance and carve elegantly. Both activities demand a high level of attentiveness and mind/body engagement to attain a state of flow.
