Pace progression

Tuesday        4.3   4.3   4.3

Felt extremely good Monday and today, so I added just a touch more speed. Just enough to average 13:59 per mile. Still taking it easy though. Woman next to me on the treadmill was doing intervals. From where I was it looked like she was ramping up to 9 mph, but it was probably 7. It was fast, though.
