...by myself, running in circles around town, in 95% humidity.
I am so tickled that I was able to do this that I cannot put it into words. It went surpisingly well. I walked for just a bit twice while I was trying to get down energy gels, but kept a really great pace (for me) almost until the end.
When I passed mile 17, I got a little emotional because last time I tried this (four years ago) I crumpled in pain at mile 17 and had to limp home on a bad knee. That was the end of my marathon training and all running for several months.
Today, mile 17 with no pain (except worn-out quads) was a sign I could make it. I did walk and even stretch a little in miles 18 and 19 because my legs were starting to say, "No more, please!"
Mile 20, though, was mine. I was at a pretty slow pace at that time, but pulled a little (what I had left of) a sprint on the last block to my house. I wish I had a picture of the completely goofy grin I was sporting when I finished and knew: I ran 20 miles today.
