On many wall surfaces, Link can jog for a brief moment before he decides to latch onto the wall and start climbing. By pressing B to let go of the wall and holding a direction that faces the wall, you can make Link move that direction for a short moment, letting him jog a bit and refill your stamina. He will then latch back onto the wall once more. Repeat the process to finish your climb or refill your stamina gauge. Most of these walls are set at most a 70 degree slope, so be careful around very sheer cliff walls. Any higher of a slope and you will fall. You can also use this trick to climb rainy slopes, but use the running animation to climb rather than the actual climbing mechanic.
