There's a pair of running shoes by your door right now.
You step over them every morning. You haven't moved them — because moving them means admitting something you haven't said out loud to anyone.
That you don't know if you can really run anymore.
It didn't happen all at once. First the pain showed up around mile one — deep in the glute, sometimes down the leg. You shortened your stride. Told yourself it'd loosen up. It didn't. So you backed off. Then the runs got shorter. Then rarer. You stopped opening Strava because watching the gap between who you were and who you are now didn't feel good.
Eventually you went quiet in the group chat. They think you lost interest. You didn't. You just couldn't explain that your own body had started saying no.
So you did the responsible thing. You saw a doctor. Then another. Maybe an X-ray. And every time you walked out with the same shrug: "It's probably just your age. You might have to accept this."
And that — not the pain — is the part that actually broke something in you.
Because you know your body. You know the difference between "getting older" and "something is wrong." But three professionals told you it was just the years catching up, and after a while you started to believe it. You started to wonder if the guy who used to knock out that loop without thinking was just... gone. If this was the beginning of the slow goodbye to the one thing that kept you sane.
I need to tell you something, because I lived this exact story, and I wish someone had told me twelve months earlier:
It was almost certainly never your age. And it was never your back.
