long run

Dolomites, seen from running path

I ran 20 yesterday since Tammi and I are leaving for a weekend trip this morning.  I just got back from an easy recovery run.  Yesterday's run was not one for the ages.  I felt fine for the first half but I felt weak and progressively slower on the back half.  What gives?  It was in the mid-50s and sunny when I went out--not hot, but I'm very sensitive to heat, and this was the first day when the sun felt warm.  I've also been training a lot and was only six day out from my last long run instead of the usual seven.  So, fine.  There are always a few times in marathon training when the wheels just come off, when you're burnt out or things just aren't working right--and these times are to be expected.  In the end, the rough patches are just your body's protest against the adjustments you're calling on it to make.
