Having run 8k last Sunday and ending up barely able to walk with sore calf/ knee on my right leg I rested for a week and tried a short run this morning. My gait felt strange to begin with but improved as I continued at a slow pace. Decided to limit myself to 3k and that took 21 minutes. Felt strange stopping at that but did and walked 3k home with no pain in leg. Planning to do a few more short runs this week and increase distance again next Sunday if leg holds up. Does this seem a reasonable plan ?
