Last time I ran seriously, around 7 years ago, I ran a 5km in 19min20s. I have not seriously ran in several years, and I have a race in a month. I intend to run a few times per week until then. What will my time end up being?

1,000I feel silly betting against you when you can just run slowly intentionally and have way more information about your current fitness than I do. But betting YES on 29-32 minutes when you ran a 19:20 7 years ago is crazy. Surely you can beat that. I only broke 19 minutes once when I was 16 at my junior year XC state meet, and yet my slowest 5k ever after that (a decade and a half later) after I got fat and put on 45 lbs (or 55 lbs from my HS XC weight) and basically stopped exercising for over a year was still under 23 minutes. If you can't run sub-25 mins I hope it's because you have a chronic health problem you didn't mention or something, because if you really let your body go that much that'd be sad.
Now this sounds insulting, sorry, but I really just hope you run fast and am reporting that I'd be surprised if you can't get 22-25 minutes still.
