So that hamstring thing was beginning to worry me. I did the best thing that I could -- stopped running. I did do 3 miles on Monday, went to work on Thanksgiving, and 4K on Tuesday. After that, I worked 14 hours on the election and got two hours sleep, so no running on Wednesday.
Started late work today, so instead of a 15 miler, I figured I'd go long just to give myself a longish run. Did 10 miles in 1:20, which I'm very happy with. Did a few miles at a fast-ish pace and it felt good. The leg is fine!
Will run a bit more the next two days then try 12 miles on Sunday. Next marathon in 10 days!
