Finally it's warm and I can't run lol?!?

Well you said you've been running all winter, i run year round also, the thing i notice when the season changes from winter or the weather gets warmer is, since we've been running in the cold weather for so long, our lungs have adjusted to the cold air, so when the warm air comes, i think that it comes in so easy, and its so easy to breathe we almost think we are having like an asthma attack when really we are just breathing normally. Another thing is do you run the same speed everyday? what i do is run faster 1 day then the next day just little more than a jog. But i hope this helps.
