Superspeed
From ALttP Speedrunning Wiki
Superspeed is a very helpful glitch, that allows link to run very fast whenever there is a climbable stairway/ladder around. In this state, Link can use items, however can not use his sword. You can cancel this state by pressing A, screen transitioning, or jumping off of a ledge, to name a few. Keep in mind that this glitch requires the Pegasus Boots, and JP v1.0.
See Spin Dash or Item Dash for ways of getting Link into this glitched state.
