Chatterbox: Down to Earth

Okay I know somebuggy out there takes cross country os something like that.  I am most likely going to quit swimming and start running, but I know nothing about it.  I am a really fast runner, and I am good at pacing myself too.  Basically all I need are the facts.  Here are some of my questions.

* How long does it take to complete the average mile?? (in minutes please)

* What is the difference between Cross Country and Track?

* If you do run, where do suggest I start myself?

* How often should I practice?

Well that's all I can think of now, but I'll have more soon.  Searching just gives me way to much to choose from so I thought I would ask you fellow Chatterboxers.  If you have any of these answers please please PlEaSe tell me!!!
