That explains it.

I went out yesterday morning but soon realised I was going to have a bad ride. We all do now and then. I stuck to an easy 20 miler but really struggled. I couldn't get my average speed over 10mph against my normal 13-14 mph. This morning I have woken up coughing and spluttering and dread to think what I am coughing up. I feel really rough. Can only be man-flu! At least I know why I struggled yesterday and a couple of days off the bike is called for.

When we have a set exercise routine, it's quite amazing how often you can spot these things coming by a short-term drop in performance, isn't it.

Get good quick.

As said, regular exercise shows up an approaching illness. Get well soon.
