Another 2 miles but more jogging

Today was a beautiful day with temps in the mid 60s. I increased my jogging from 40 seconds per phase to 50 seconds per phase. The resulting jogging:walking ratio is 50:60, and that sequence is repeated for the duration of the run. I felt fine during and at the end of the run. I took no rest breaks on the way out but took two breaks on the way back.
