No Good

Oh dear.

I was doing so well.  A reasonably long effort (48 minutes scheduled) with strides every five turned into one lap around the Reservoir and a slow, painful walk to the train home.

The effort was really good.  I started out with a nice warm up, averaging a 150 HR, followed by three solid sets.  Each main set was keyed in to around 9:50 and each set of strides was right around 8:00.  Good HR throughout, averaging around 162.

Then my left hamstring suddenly seized up and I couldn't run any more.  I pulled over and started to rub out my leg, and as I stood there my right leg started to tighten.  I decided to try to run through it as though it were a cramp.  That lasted about a minute, during which time I averaged about 13:00/mile.  No way.  Then I started to worry that I was going to tear something if I kept it up, so I stopped.  Ugh.
