Thoughts for an Early Weekend Morning

I'd rather still be sleeping. But...Nothing boosts confidence like doing something you never thought you'd be able to do. Since I was wide awake for no apparent reason at 6:30 am, I went for a long run near my neighborhood. It's a route with about 7 hills, two of which are super steep, the others which are longer gradual rises. When I first started doing a shortened version of this route back in like May or June, I walked most of the hilly parts. I just couldn't make it up...like a Loony Toons character, I'd be chugging away and then grind to a halt part way up the hill. I've slowly improved on the hills and added mileage to the run. This morning, I made it up 6.5 hills and made the run a 4.5 miler. If I can do that, surely running 6.2 on a fairly flat course will be doable in about three week.
When it came to school or work, I've always been confident in my abilities. But in the past few years, I've felt that my body was on the downhill slide into old age and there was nothing I could do about it. I never thought I'd be able to run this far or fast again. I never thought I'd be able to get back in shape (30 lbs down 20 to go!). But I have, and I gotta say, it feels awesome! If I can do this, I'm pretty sure I can do anything at all.
