My wall runs have really come along. In a 10ft hallway, my face now comes close to touching the ceiling, and my hands can very easily touch it. Of all the things in parkour, I think I like this movement the most. It feels so fluid and effortless, yet satisfying.
Here are some of the things I've learned:
* Ankle tension is key (how much?)
* I can't ask myself if I'm doing it right. I know when I'm doing it right.
* It can't be forced.
* At no time am I not in control of my momentum and movement.
* Foot placement still frustrates me. I really want to take off on my left leg, but I have to be the proper distance from the wall and everything. This is the hardest one.
* The surface appears to matter. Smooth surfaces tend to frustrate, but I feel very little downward pull; perhaps, with time, one's control increases to the degree necessary to wall run up anything.
* I have not yet tried to do this and actually grab on to something.
* I'm still skittish.
* What I have in muscle, I lack in stamina.
