I hope you aren't all tired of hearing these w5r3 posts! I love reading every one and I had to share too. I ran for 20 minutes straight today. This is the longest I have ever run in my entire life (almost 40 years)!!! THAT is exciting! I was athletic and strong as a teenager and into my 20s but could never run far. I couldn't get past the burning lungs. By week 3 in the program, my burning lungs were gone. Today, the first 15 minutes was good, the last 5 minutes I had to slow it down even more and really push through, but I made it! I almost shouted for joy at this new milestone (too many people around or I would have). I feel like I overcame a huge mental hurdle and I have no doubts about the rest of my runs now and my ability to do this. Thank you for this program and for all of you spurring each other on.
