I have been a competitive runner since college and continued racing into my 40s. But now as a 60 yr old, I'm starting to lose interest. The runs are shorter, less frequent and not really fun anymore because they're getting harder for me. I try to be consistent and it is frustrating that I can't run nearly as fast (which I understand) or far as I used to. I wish I can even enjoy the short runs I go on now. Anyone my age feels this? And what if anything did you do about it? I miss the old days when I felt like I was flying.
