Training this winter

I havent got asthma. as far as Im aware, anyway. But I was doing some turbo stuff this morning with the balcony door open and the cold air was giving me sore chest, almost like a cold feels.
What does asthma feel like? Sometimes I feel I just cant quite fill my lungs as much as I want.

Cold air won't be great for anyone's chest. Especially with all the bugs flying around.

What does Asthman feel like? Thats a really good question. The medication I use now is so good I forget I have it. Its only when the medication runs out or I'm killing myself on the bike that I feel it. You experience a wheeziness and a difficulty to fill your lungs.

When on the track last year I was getting to a point where I couldn't get enough air into my lungs, forcing me to stop. But I think this was as much about technique/posture/condition as asthma.
