Over the past couple of days, my head has been slowly filling with gunk. I seem to be full of phlegm and it seems to be coming out of my throat, nose and even eyes when I sleep. Over the past couple of hours I seem to have developed a light tickly / chesty cough too which feels like my chest is receiving it’s share of phlegm too.

Funny thing is though, I feel fine. Don’t feel ill at all (yet?).

I also have a marathon in around 6 weeks I need to be craking on with training for and a Triathlon not far behind it.

Am I OK to carry on training or will it result in certain death? I need to be getting the miles in if I want to complete this Marathon.
