You'll wreck your knees!!

The Long Run Mindset - For a Life Worth Living #8

“You’ll regret that, Andy.”

The person at the bus stop points at my mud-caked trainers. They’re leaning on a cane, barely sixty. “Running ruins the knees. Friction, mate. Like brake pads wearing down.”

I nod. I keep moving. I’ve heard it a thousand times. It’s the biggest lie in health.

THE STORY

My physio, Mat, comes to the house. Costs me £40. We’re in the kitchen. No waiting room. No elevator music. Just the truth.

“Andy,” he says, leaning against the counter. “My diary isn’t full of ultra-runners. It’s full of people who live on the sofa. Their joints aren’t worn out. They’re seized.”

Mat tells me about his other patients. Not ultra-runners. People who stopped moving years ago. Their joints aren’t worn out — they’re seized. Stuck solid from the inside.

“They get three basic exercises from the NHS,” he says. “Simple stuff. Just to wake the muscles back up. But they don’t do them. Too much effort. Too pointless. They’d rather wait for me to fix them with my hands while they refuse to move their own legs.”

Then there’s Fiona Oakes. Had her entire right kneecap removed at 17. Doctors said she’d be lucky to walk. She ran marathons on every continent and broke world records. No kneecap. Just the refusal to accept the story someone else wrote for her.

Here’s what nobody tells you: running is linear. The same movement, repeated. It’s the twist that breaks knees — the Sunday League tackle, the sudden pivot, the torsional snap. Those are the real killers. Running? Running is the grease the engine needs.

But we’d rather buy the solution than do the work. People drop £180 on shoes with enough foam to float a boat and wonder why nothing changes. They won’t spend £40 on someone like Mat to tell them their gait is a wreck and their glutes have been asleep for a decade.

THE LESSON

Your body isn’t a car with a fixed mileage. It’s an adaptive machine. It gets stronger under stress — if you respect the mechanics.

The exercises Mat gives you aren’t pointless. They are the blueprint. But people would rather buy a new pair of Nikes than do ten minutes of glute bridges. The human knee is a masterpiece of evolution, but it hates being stagnant.

Rust is a choice. Motion is the cure.

YOUR TAKEAWAY

Stop listening to people who haven’t seen their own feet in a decade. If your knees hurt, don’t sit down. Fix your form. Strengthen the chain. Pay the professional to look at your movement, not your shoes. Stop waiting for a miracle and do the work.

Don’t save yourself for death. Arrive at the finish line completely used up.
