no riding at all for fear of it having been a viral infection.
This is very good advise.
I did some medical training while in the army, and one thing I learnt a lot was how easy it is to get asthma when one pushes themselves while thinking they only have a cold! Please do NOT listen to that nonsense of people saying "I'll sweat it out" you can not sweat a virus out. If you feel it on your chest or have a cough with it then please rest it out another couple of weeks, I used to do a lot of fell running and competed quite a lot, even though I aren't a 'runner' I used it as a training tool for my riding and rowing, I'd always finish at my worst the top 5 but one year I knew I didn't feel right, right from the start I felt quite bad but being an ex para is something they drum into you to forget about pain and so I just kept running, I managed to finish top 10 but later that day got sent straight to hospital suffering from hypothermia! Take it easy out there.
