Today I did my walk/run thing. I walked to my nearby track and did some intervals, running the straight part of the track and walking the curves, about two to three laps of that. Then I walked out of the track and to the street. Walked my way back to the house, walking and sprinting the uphill parts for a total of 3.42 miles. Today it felt different than previous times, no pain on my feet or shins whatsoever. I call that progress. The goal is to be able to just run the 3 miles instead of the run/walk.
