I was diagnosed on October 3rd last year with non small cell lung cancer. Had the upper right lobe removed on November 15th. Luckily it was stage1a so No chemo or radiation needed.I signed up for a fundraiser walk for American cancer society that covered the month of December and walked over 160 miles. Since then I’ve been walking a lot, over two hundred mile last month. I’ve been trying to transition to running but get winded very quickly. It doesn’t take too long to catch my breath back if I go back to walking but I can only run (jog) about half the time. Will this ever get better? I want to do a 10k or a Half marathon but right now not sure I’d make the cut off times. 14-15 minute miles is about all I can do so far. I was in good shape prior to the surgery but wasn’t a runner so don’t have a good idea of how I would of done before this mess. Any insight on what to expect appreciated
