Walk breaks, pt 2

I did my first long run using my new plan today, a 7 miler with 1 minute walk breaks between each mile. I had an average pace of 11:10; when I checked my log, that pace is pretty average for a 7 mile run. So walk breaks didn't slow me down at all; didn't speed me up; it just meant I managed to complete the miles without feeling dead tired at the end. And the run seemed easier. Whenever I started feeling tired, I could just remind myself that I only had x distance to go before I had a break. As I ramp up the mileage on the long runs, this could make a huge difference.
