Marathon

I was watching KCSG, the St. George news station, and there is an 84 year old guy who runs the St. George marathon. Wow.
I have had an urge to run for the past two years or so. I have wished I was a runner, I love the feeling of running, but I hate that I am so weak and so out of shape that I can't do it. I really want to do it!
I think I will do it next year, the St. George Marathon. I know it sounds crazy, but why not? I can build up to it, it is in a year, afterall. It will give me inspiration and motivation to keep exercising and to be healthier.
But
marathons are 26.2 miles!
I can do it. Maybe there are other short runs to try to build up to it, too. I know there are, actually. I just have to find them!

What do you think?
