12 mile run today

Yesterday I spent working all day working on my pacing robot. I decided to take the day off since I was feeling very tired. I may have been fighting a virus. I ended up having a great time playing the piano in church with a good bass player and drummer. I had someone say I sounded like Vince Guaraldi which was a huge compliment. Today I felt good and decided to go for a 12 miler. It is the longest I have gone in a while for my long run. I through in some surges and felt like I was activating dormant muscle fibers. I think it is imperative to do at least one long run per week in order to maintain aerobic fitness. My long run now is going alternate between 12 and 14 miles.
