How impressive it and how durable would you need to be? Presumably your legs would need to withstand all the kinetic energy built up? I am guessing you'd need to be over Spider-Man a level to pull it off?
@gxrevs06: Doesn't matter how high you fell from. What matters is the velocity you had before you came into contact with the ground. It takes about 450 meters of height for you to reach terminal velocity, and for a typical human that would mean attaining a speed of around 53 m/s.
