I can only speak for myself. I imagine it all depends on a persons condition when they start. For me, I'm 49 years old and I smoked for 28 years, had a desk job for 6 of the last 12 years and had done nothing for the past 5 years. When I started I was about as bad as it gets. I also tend to use the word running interchangeably with jogging.
When I first started C25K I was jogging at a pace of 12 minutes per mile or 5 miles per hour. I suspect there some people that can speed walk at that pace. Whn I walk I go at 4 miles per hour. Today, I jog at a pace of 6 miles an hour or so. Once I get back up to running a full 5K I will then start to work on the pace.
I can say, at this stage of my conditioning, my lungs and breathing are no longer an issue. It's my legs (muscles and joints) that give out first.
