Here's my tracking data. You'll notice that I started walking more and more around mile 18. Considering that due to injury, I hadn't run more than 16-miles in training, and that was several months ago, it's not surprising. Also, by that time, my knee (thanks, hamstring and IT band) was more and more painful.
