Turbo button?

Hi guys, this is a noob question but I can’t figure it out. Anyway to make a character move twice as fast by pushing a keyboard button or other sensor? Is this possible with just Logic Bricks or do I need python?
Thanks in advance!

keypress w----------------and---------------walk
kepress shift invert-----/

keypress w -----and--------run
keypress shift-/

thanks that was so easy!!!
