The engine survived

Here’s a question I asked myself mid-run this morning, somewhere in the tight-legged, heavy-limbed middle of it: has my endurance taken a hit?

The illness really took it out of me. Two weeks of a cold that settled in my chest, and even now, a few days back on the road, my legs feel tighter than I remember, heavier, like they’re running through something. So the worry crept in — all that base I’ve been patiently building, did the fortnight on the couch undo some of it?

And then I looked at my watch and noticed I’d been running for over an hour.

Oh.

Right.

Because here’s the thing I’d managed to forget while feeling sorry for my tired legs: you cannot do a sixty-six-minute run on an engine that’s packed up. The very run during which I was worrying about lost endurance was itself the proof that my endurance is fine. Over an hour on my feet, strategic walks and all, three days out from being properly ill. That’s not a diminished body. That’s a body whose base is completely intact, just running on a tank that hasn’t quite finished refilling.

That’s the distinction I keep having to relearn. There’s a difference between endurance — the deep capacity to keep going, which takes months to build and barely budges in two weeks off — and freshness, which is how good you feel right now. My endurance is here. My freshness is still catching up, because my body spent two weeks fighting a virus and is only now topping the tank back up. The tight legs aren’t lost fitness. They’re the receipt for a recent illness, and they’ll fade.

So I was being unfair on myself. The heavy legs told me a scary story, and I nearly believed it — right up until the clock quietly called their bluff.

The engine survived. It always does, if you rest when you should and come back gently. The legs will feel like mine again soon enough. And in the meantime, I’ll take “ran for over an hour while doubting myself” as exactly the kind of evidence I needed.

Doubt your legs if you must. The clock doesn’t lie.
