I just run up on all fours and see how far I can extend my limbs to the next step

I always put my hands a few steps ahead so it's even more quick.

[mlockha]

Lol, I always just go up on all fours , quicker, without skipping steps. 

This.

[Jubel]

I go up three at a time.
Lol, doubles.

[Tremrist]

I like to pretend I am mountain climbing, hang on to the railing and step up 4 or 5 at a time.

[Camera]

I quadruple step because I think it builds leg muscles.

[Sulfate]

I usually trip if I try skipping stairs, SO₄ most of my journeys up stairs I just take it one at a time.

your move, skip

if you can't double step with a hand rail you are either physically unable or a loving handicap.
