I'm a first time poster too. I'm really trying to reach high with my goals but I have to say – I am inspired by Amy's ambition. I'm 27 years young, 5'6″ and 160lbs, I can run 6 miles without breaking. I run 6 miles in 63 minutes and it just about kills me. Getting past a 5k isn't much trouble but I don't think I can run it that fast. I've heard of guys in the army getting the best times of their lives at 18 minutes for a 5k. Amy's goal is about that tough. Good luck Amy, I'm really impressed by your goals.
