Marathon worries

So I went to a Wednesday run today. I haven’t been for two months, but I feel like I’m totally out of shape. Running up hills was taking a lot out of me. So I’m starting to get worried about this marathon I’m running in eleven days.
I’m accepting that I won’t be able to make my time goal. But I’m worried I won’t finish. The past few runs I’ve done seem to take a lot out of me. Mind you, most of them have involved hills, and there won’t be any in Manitoba. And it has been hotter in the afternoons, and I’ll be marathoning in the morning.
I can only hope.
A person at the Running Room commented that it looks like I’ve lost weight. I don’t know if that was in the good way (lost fat) or the bad way (lost muscle).
Well, more things to worry about.
