I’m no where near it right now I probably am like a 19:25 5k runner right now as I have been building my base with lots of easy mileage. I’m scared as I’m not used to being this slow so I have no idea if it’s normal. Like will I get way faster after base phase and start sharpening?
This track season I probably ran no more than 30 I couldn’t PR.
Just keep running and the improvements will come. There’s no secret to achieving an arbitrary time, other than being consistent and staying injury-free. I would say to be careful doing workouts during the summer, but don’t neglect tempo runs and hills. I’m 10 years older than you and got back to running middle distance this spring, setting PRs from 800-5k on low mileage (~30-35 mpw), but I was occasionally hitting 50 mpw before I got a coach.
Good luck, and have fun!
