Hills and a Tempo Run

Wednesday brought hills: (60, 75, 90)x2.  A cold day to run and tough hills - but I felt strong running it - and my back held up nice.  Friday I had to go by myself.  I did the 4.7 loop - but ran 3.8 of it fast - a 7:3something pace.  3 pretty solid workouts this week.  Next week brings a 11-12 miler and more hills - but feeling pretty good about the approaching half.
