Thanks for the feedback. I was starting to feel better running when I was managing to get 3 runs a week in consistently in Mexico. But that hasn't happened for a long time for various reasons, so I am not surprised that the same meager distance seems harder (and I'm slower) than in the past. Just gotta keep plugging away! On the plus side, my riding is going better since I am doing more of it. Been getting in two or three 30-35 mile rides weekly, and that fitness seems to come back pretty fast for me (vs. running, which has always been much more difficult for me).
