I was diagnosed with chronic cold/exercise and allergy induced asthma at age 4 some 67 years ago. Through necessity I discovered that I could run through an asthma attack as the eventually it would mitigate somewhat. I did up to 4 mile runs down to 8 degrees that way for decades.

Even today with the beta-agonist rescue and time-release inhalers, I sometimes have to do the same thing both running and cycling, but it's infrequent now.

My regime is to do Serevent every 12 hours. About a half hour before I start exercising I'll do one puff of a rescue inhaler (Albuterol) . About 10 minitues before the start of the ride I'll do another. If it's cold, I may do another a half hour later. That generally does it. If it doesn't, I'll tough it out.

These beta-agonist inhalers can kill ---- sudden death. Too many puffs too close together does it. They need to be spaced out.

I suspect that the victims have really severe asthma and are not in good shape.

Experimentation is worth while.
