Today, I decided to do a smaller loop of 6.5km. I noticed that the soles of my foot is slightly hurting because the bottom of my shoes are worn out. Even though the outside doesn't appear to be broken or worn, the soles themselves are worn. I did however work on some speed today. I did a few intervals of sprints followed by intervals of my normal pace of jogging. Workout Summary: 6.5km Time: 30 mins.
