I have never liked running. I would prefer to ride a bike, but I know that running is actually a better cardio-vascular workout. Plus, I have that goal of running a marathon. That's not a "bucket list" kind of thing, though. It's just something I've always wanted to do. I don't plan to expend all this effort; run the marathon; and then give up running altogether.
On today's run, about a third of a mile out, I thought, "Why the hell am I doing this?"
Right now, the only only answer I could give was, "Because I want to."
For now, that's enough.
