Just come limping back from W6R2 😡 Was half way through the second lot of 10 minutes and feeling good when I felt a slight tightness in my left calf. Thought it would run off but then a sharp pull and it felt like someone had my calf in a hot vice!!! Stopped and stretched to no avail and had to walk back. Felt loads better by the end but when I tried to run again it felt really painful and tightened up again 😩 Looks like I will have to make do with daily hour long brisk dog walks and start week 6 again on Monday. Don't want to rush it and cause real damage. Does that sound like the right thing to do?
