Of course you can do it! I relate to the running thing, I am a horrible runner and I hate it! That being said, I want to conquer it! I have never been able to run more than 3 or 4 miles at a time, and that was at a pretty slow pace (even when I was in shape). It's been a couple of years since I ran so right now I probably couldn't do a 1/2 mile. But I am determined to add a half marathon to my list of goals...I might be crazy ;) Good luck!
