Training for 10 mile run in December

Alisons_goal

Hey, I am wanting to run the 10 miler Dash for Cash in December but I'm not sure how to train. I mean, run obviously but like what pace should I try? Like, increase by a mile every couple of weeks? Should I run flat surfaces or hill? I just don't know where to start really. The longest race I ran was a 5 miler and I couldn't run the whole thing.
