Lunch Run

6K at a mostly 5:00 pace at lunch today. Things are hurting a bit. I gauge the level of activity by how I feel when I get out of bed in the morning and walk down a flight of stairs. Last couple of days have been a bit sore and stiff ... quads complaining! I am working 12's on the weekend. I am planning on a 14 and 16K run both mostly at a 5:00 pace.
