I got up this morning and ran another 13 miles, to complete the marathon that I started yesterday. Naturally enough, I was much slower this morning. I didn't have the crowds or the adrenalin to push me along. And, of course, I was that much more tired before I even began. But I ran the whole thing, including running the last four miles straight. In three weeks, we'll see if I can do that without the twenty hour break between the first half and the second half.
