Puffed VS Asthma

xSuperNova

When I first started my journey, I could only run 1 minute before needing to stop. All though I've lost a lot of weight, I've only recently increased that time running to 4 minutes.

I really want to play soccer this year, starting around March. Obviously I'll need to be rather fit.

My problem is that as a child I always suffered from asthma ( I don't use an inhaler anymore), and because of this I have no idea how to distinguish between being puffed and struggling to breathe due to asthma. Can someone explain to me how I should know when to stop running? What does it feel like to be just out of breathe from running too much? How can I tell if I'm struggling to breathe due to asthma or just pushing hard?

Thanks (:
