The plan was to try to run for an hour and a half. Slow and easy. I did a little more walking than my normal 2 minutes run to 30 seconds walk. My milage frame of mind wouldn't let me quit at an hour and a half. I decided to go ahead and get in 8 miles. Garmin said 8, Nike app 8.3.
It seems like if you slow down enough you can go forever. I think my average pace was about 13:30. Normally it is about 12-12:30. I always tell myself, "don't try to compete with the young folks...your goal is to not get hurt and continue this great exercise program." So, I try to keep it pretty slow. I think I'm going to read up on the 80/20 running plans. 80% slow and 20% fast. Supposedly, you get faster overall.
