A 20 Minute Swim and a Run to the Post Office

I've been fighting a cold, an although the Zicam swabs have helped to keep it at bay, I decided to take a rest day yesterday. The weather today has been like a summer day with morning temperatures in the low 70's and midday in the low 80's. I cut my swimming to only 20 minutes this morning. I decided to literally run to the post office, so I did 1:00/:30 intervals there and back. The total trip, with traffic lights took 38 minutes.
