I run and I feel like I am going to die. I want to be able to run and feel good like I hear people say they feel. How do I accomplish this? How long until I can run and just run for fun? I am about 200lbs and 32. I have some decent Brooks running shoes. I want to run outside. Thoughts on how to get started and how to reach a point where running becomes like walking and not where it feels like death?
