I had to stop in the middle of week 4. At that time, I thought it was common cold. Unfortunately it is some sort of infection going on.
After trying day nurse/night nurse for about a week with no effect, I went to the GP today. Got antibiotics prescribed.
I will have a recovery of between 3 to 5 days. I plan to restart with week 3 once I feel 100%.
The main issue I have is I have signed up for Great Scottish Run this Sunday.
Looks like I will be walking most of it and simply aim to finish it in one piece.
I will just be glad to get back on track after being derailed.
