I don’t know if I’m actually asking a question or just looking for commiseration. I started running 10 years ago (34yo) and took to it pretty well. I wasn’t the fastest but got better with miles and at my peak ran a 30:29 5k which was amazing! I got burnt out so I switched to spinning about 6 years ago and have kept up my fitness ever since working out 4-5 days a week and running on a treadmill sporadically. 6 weeks ago I signed up for a 10k (which I completed today). I figured since I kept my overall fitness and cardio up I could pick up on my low end which was 12-12:30 mm. I was so wrong. Training outside felt like I was trudging through mud and when I finished I felt like crap for the rest of the day. I started with 14-14:30mm and one run was great at 13:30mm. I feel so defeated. It’s not fun and it feels awful. I’m more mad because it’s not like I’ve sat on the couch for years! I’m so active. I feel a big part is, obviously, I’m older but I’m also in menopause and haven’t physically felt like myself lately. I just wonder has anyone else experienced this? I finished my 10k today but I was basically useless for the rest of the day. I’m older but I’m not that old yet!!!
