Jeeze, what happened to me?

After the October race, I determinedly set-about doing a long run once a week to stay in shape for Boston. I ran the same 19 mile course every week and pushed pretty hard the whole way each time.

Now, having run little over the holidays and gained a few pounds, I am out there stinking-up the place. Last week I had to walk the final 4 miles, this week I "ran" the whole thing, but the final 6 miles could have been walked faster than I ran them.
