Twelve steps. The physiotherapist had drawn a line of tape on the floor and said, quite gently, that today twelve steps would be a triumph. I looked at the distance between the parallel bars and the tape and thought: twelve steps might as well be twelve miles.

Six months ago I had run a half-marathon. Then a car, a wet road, a sound I still cannot describe, and eleven weeks of learning that my own legs had become strangers who no longer answered to their names. Now I stood between the bars, gripping until my knuckles blanched, and asked my right foot to move.

It ignored me.

I asked again, not with words but with everything below them, the raw animal wanting that lives beneath language. And this time — grudgingly, as if from a great distance — the foot slid forward. One. The bar shrieked under my weight. Sweat stung my eyes. Two. My bad leg buckled and I caught myself, arms screaming, and hung there shaking like a puppet with half its strings cut.

“You can stop,” the physio said softly. “Two is good. Two is real progress.”

And there it was — the moment that every determined act is actually made of. Not the cheering, not the finish line. This. The quiet offered exit, the open door back to the easier thing, and the choice to shut it. I thought of the tape on the floor. I thought of the person I had been at mile ten, legs full of fire, certain the body was a thing you simply commanded. I was not that person any more. I would have to become someone harder.

Three. The pain was enormous, a white noise filling the room. Four. I stopped thinking about twelve. Twelve was a lie; twelve would break me. There was only ever the next one, the single next step, the whole universe narrowed to the six inches of floor in front of my trembling foot. Five. Six.

Somewhere around eight I began, absurdly, to cry — not from pain, though there was pain, but from a fierce and private joy that had nowhere else to go. My mother, in the doorway, had her hand pressed to her mouth. I did not look at her long. Looking away was itself a kind of strength; the steps needed all of me.

Eleven. Twelve. My foot crossed the tape and I collapsed into the physio’s arms, ruined, laughing, remade.

She lowered me into the chair and crouched to my eye level, grinning. “Same time tomorrow?”

I wiped my face. “Make it fourteen,” I said.
