Wooohooo!!!! Thanks =)

3:45 is an awesome marathon time... I have no doubts that you can do it! As for getting better at hills, I've found that running/climbing/crawling up and down a mountain works best, if you have any of those around. Or setting the treadmill at the highest incline and walking as fast as you can (it hurts!!).

That reminds me of the time I saw a nearly naked man in my gym posing in front of a camera. I guess he was making a body building video or something... all he had on was the teeeeeeniest tiiiiinest g-string. And he wasn't, shall we say, blessed with large hardware. Or even medium, or small to medium. Nope. I almost felt bad for him. And of course, once you see something like that, you can't UNsee it. It's like looking at roadkill- it's nasty and gross but you just can't help but look.
