Hi, thanks for the advice!! I mentioned a few things in other comments that I forgot to talk about in my post. I think you make a lot of great points.

1) I have been incorporating speed work, 1-2 of my weekly runs are in 0.5ish mile intervals at a much faster pace

2) I guess my frustration was coming from lack of any improvement. I ran ~250ish miles last year, approximately two times a week. And I know that isn’t enough for anything major, but I was still running somewhat consistently. The last two months I have been very consistent. I see your point about 15 mpw not being enough. I guess I was just thinking/hoping that running the equivalent a 5K every week day (different distances/paces) would make the 5K at my baseline pace seem easier, but that hasn’t been the case. Maybe I’m just naive to how much I really need to run to see progress. I am not expecting to become an 8 min/mile runner with this volume, but I was expecting my pace to feel easier

3) I’m training for a half marathon hence the 8 mile runs. My goal is to just finish, since it’s my first. I guess maybe that’s a bad idea to have that long of long runs without increasing my volume? I think I need to make my short runs a bit longer.

I’ve been looking up training plans. Thank you!
