Time to rest for the 5K on Saturday

I decided to run the 5K on Saturday. The race is sponsored by the swimming club at Magna High School. My 10-year old grandson is taking swimming lessons from the club. Today I ran two miles, going from 10000 South to 10600 South and back. The shade temperature was in the mid 80s (F), and it was a pleasant day. I didn't go particularly fast and just enjoyed myself. My purpose in the run was to loosen up. If I ran fast and hard this week, my performance wouldn't improve, because our bodies take more time than a week to adjust to stress. Running fast and hard would tire me and likely hurt my performance in the race.
