GPS With Objective C

I want to make an app where you can run with your phone, and it can keep track of how far the run was in miles. How would I do this?(I just completed making the BlogReader app on the Objective C course. Are there any more tutorials I should go through on the Objective C track before making an app like this?).

Look up using CLLocation.

Thanks! It seems useful! How should I use it in my app and make it so that one CLLocation instance is updated as you run and one stays as the location where you started running and isn't updated? Also, how can you calculate the distance between to instances of CLLocation? Thanks, Kirk.
