I am too fighting my 2nd cold/flu, the first one i got when i raced track cycling at the velodrome 100kms away and it was right next to a mountain that they were having troubles controlling a bush fire on, and had been for weeks and all the smoke had settled into the velodrome, i was unable to breathe between races and don't suffer from asthma or anything. then that lasted 5 weeks before i got over it, and then just got back into training for 2 weeks and then got sick again and this has been about 2 weeks but no where near as bad. the funny thing is the guys don't understand how i am riding so well being sick, coz i am still beating them, must frustrate them. but i have had a few days off bike again and hopefully i'll be all good.
