I made it 22 miles today!! Pace was easy, but except for a short period around mile 13 when I thought things were going to tighten up on me, it went well. Slowing down a bit made that go away, and although I was definitely tired, I didn't feel completely spent. The marathon may end up being slower than it seemed I was able to do before the leg thing, but it shouldn't be a problem to run it. I will be happy to just finish.
