How does one express "until" in these sentances?

I will wait here until you say you're sorry.
Здесь буду оставатся...ты говоришь, что ты сожалеющий.
I kept running until I was tired.
Я продолжал бежать...я был усталым.

Is it just the word "до"?

[EDIT] And another question that I don't think deserves another thread. How do you express "any", as in "I don't know any of the answers."

Thanks
