Last winter I had Glandular fever and was off my bike for 3 months. As soon as I felt fit I started training and by Summer / early Autumn I was at the peak of my form. However about four weks ago my strength collapsed and I have been reduced to struggling to walk to the shop. I am told it is a "post viral fatigue" and it feels like my body has died or aged fifity years in a few days. My dotor tells me I overtrained after being ill and my immune system has been ruined and left vulnerable to all sorts of things. As soon as the weather has turned I have caught whatever virus's have been going around and I have basically been left physically wrecked - he called it a physical breakdown. He says it will pass, though I have to be careful not, by over exercise to make myself vulnerable to Chronic Fatigue Syndrome (ME) or the like. Apparently this typically attacks people who push them selves too hard physically.
Has anyone got any experience of the symptoms of over-training or Viral Fatigue? Does anyone have any tips on coping with this and building myself back up to a level of strength beyond gentle walking? Right now four weeks into this it scares me to think how long I will feel like this and when my body will start to feel strong again.
