I don't think the infection was related to the long run, more probably the outbreak at work. At least I get paid sick leave.
This morning I decided I was fit enough to try a short run and headed to the woods. I took it very easy but was relieved not to experience any ill effects, save a lack of training.
Hopefully things will be fine tomorrow.
Incidentally, the only after effect of the Cuckoo Way is a single black toenail.
