How do I make my animation go faster?

I have a simple running animation for my first character, and it seems that any value above around 60, when put in for animation speed, will not make my animation any faster.

here is a demo if what I am talking about:

so... How does one go about making this guy run faster?

edit: no URLS? Why?

If 60 fps isn't fast enough that means you need less frames - just use every 2nd frame, for example.

How would i say do that without making many new animations?
