Hard Running.

or running hard.  I did 5 miles Friday with Larry sub-8.  Then we did another 5 Monday ~7:40-7:50.  It was hard, my lungs were searing.  Today I was by myself and I did the loop in ~40.  I didn't run hard, but did 2x3:00 pickups for fun.  I was surprised that I came in at 8s, since the rest of the pace felt pretty slow.  Tomorrow I'm up to Boston house-hunting.  I should be able to get another run/swim in Friday.  I was planning on swimming - but the weather looks pretty nice.
