First off, there is absolutely nothing wrong with doing what makes you happy. Finding something you enjoy doing every day is so important, and it will serve you well throughout your life. You never have to force yourself to do anything you don’t want to when it comes to running.
I have struggled immensely with the exact same feelings as you. I competed at a high level in high school, college, and then post-collegiaty. The workouts (and races) were always a major mental hurdle in high school and early college. I dreaded them. Even days before a hard effort, I would struggle to relax and sleep. I always felt my heart-racing, stomach fluttering, and actual fear leading up to the “big day”. Fast forward to my senior year of college. I upped my mileage to 80-100 and took the workouts much much easier. I didn’t hammer myself into the ground like I had been. The anxiety slipped away because I knew I wasn’t going to push myself into a dark place. I also started racing “from behind”, meaning I would intentionally go out slower than I needed to and only pick it up when I started thinking “this isn’t so bad . . . I bet I can pass that guy just ahead of me.” All of a sudden my PRs dropped substantially, and I was a lot happier.
If you ever decide you want to do workouts just to add some variation to your daily training or to prepare for a race, treat them as nothing more than optional and unimportant. Don't push it to the point of discomfort. If you do a “tempo” run correctly, it should leave you feeling invigorated, energized, and hungry for more. Don’t hold yourself to any set times or distances. Don’t plan out the workout beforehand. Try picking up the pace only when you feel good. If you start feeling anxious and uncomfortable, just slow down to your easy pace and enjoy your regular run. Even picking up the pace for 30 seconds and then slowing back down is totally fine. Give yourself permission to stop whenever you’re not feeling it. And if that means you’re never feeling it, that’s totally fine too. Another poster mentioned that it helps to only pick up the pace at the very end of a run. That’s great training! Nothing wrong with that. I’ve noticed that when I tell myself “I’m doing a hard workout” and start out fast, it’s mentally much more difficult than starting at a very easy pace and picking it up for a bit—only if I want to.
The perfectionist mindset is hard to shake. I have that to an extreme degree too. It got so bad for me that I started racing under a fake name because I was so anxious that people would judge me if I had a bad race. Now, no one knows who I am when looking at the results, and I actually have fun at races. I purposefully ran 2 or 3 this summer that I wasn’t in great shape for just to prove to myself that it’s ok to go out, do your best, and get your butt kicked with a smile on your face. You can really enjoy running, working out, and racing if you give yourself permission to have fun and enjoy the process without self-judgment. Good luck to you!
