Help With Breathing ?

taterbug29

Hi,

I've never been a runner but would love to become one. I've tried the C25K in the past along with lots of other things. My body doesn't get tired but I have to stop anyway because I can no longer breath. I'm talking about having to stop after about 2mins of jogging. My doctor is currently doing lots of test on me to see if there is an actual cause, as I can't even walk and talk for more than 100yards without being out of breath...even when I'm in the best shape.
There is a 5K I would love to run in July but I can't even get passed week 1 of the C25K. Any advice would be greatly appreciated.
