I'd like to be able to sprint and jump. this should have been included in the game.

Not last I saw, and it's been suggested many times. It's too involved in animations to be workable right now.
Still, we can always hope that Dawnguard will help, if not by introducing it, but by making that particular animation setup a little more flexible.

I've been also meaning to make a thread on this for like forever. I can't fathom why they didn't put this into the game.

You had a sprint jump of sorts in the first mario game...
