Trying to build mitochondria with some  600m repeats tonight.  1 mile warm-up and stretching. On the 800 m cinder track. I ran 600 and walked and jogged 200. The 600s were at eight minute pace. (3:00) The recovery was less than three minutes.

I was cautious because of A complaining right leg hamstring muscle.

The workout was positive, but I will need some time off to be sure my hamstring muscle is cared for. Tomorrow will be swimming, whirlpool, and weight room. It’s just about one month until thePan/ Am Masters games. So I cannot afford a hamstring injury.

Stats are positive-
