I ran for 2.25 hours today. It's been quite a while (too long) since I did a run longer than about 1.5 hours. That last 45 minutes... harder than the entire rest of the thing.
That's life, though, ain't it? Putting the finishing touches on a book is often harder than writing the first draft, doing the last few bits of a housework task seem harder than doing the rest of it. I'm working on being the kind of person who finishes what I start, and the running can train me to do that.
And now, because I ran 2.25 hours, I'm off to bed. :)
