Is "Run It" a sport, or a legalized medical catastrophe? I’m breaking down the biomechanics of the most dangerous contact sport you've never heard of. With collision forces reaching 16,800 Newtons—vastly exceeding professional rugby tackles—this isn't just a game; it's a high-velocity recipe for Diffuse Axonal Injury and long-term CTE. As an orthopedic surgeon, I’m analyzing the physics to show you exactly what happens when the human body acts as the crumple zone. We’re discussing the medical reality, the tragic risks, and whether this design belongs in North American sports. Stay medically literate. 🔪

My position in plain language: RUNIT is not a sport with a safety problem — it's a safety problem designed as a sport. The force numbers are not close calls. They are catastrophic-injury territory, by design, every single time.

That said — I'm genuinely uncertain whether banning it does more good or harm. Prohibition moves risk underground and removes medical oversight. What do you think is the right call?

And I thought slap fighting was obscenely deranged.....

Going senile in their 40s or 50s must sound like fun to these people.

@JLLockwood 2 months ago

I feel the same about slapping, it’s basically speed running brain damage.

Rugby is getting supper strict about ANY head hits yet somehow this has been spun out from it.

@TheRogueSociologist 2 months ago

This is not a sport, this is a speedrun towards a life on disability.

Next up, F0 racing, two F1 cars just crashing together, seems like the way things are going.

Run It and Power Slap are essentially speedruns to CTE

Next sport up:
Ground Chicken, wherein which skydivers jump with no parachutes so they can try to dominate the ground during collision.
It will be televised.

As someone who has played rugby for nearly 30yrs of my life, I’m so glad to see someone addressing the huge difference in force between a normal rugby tackle and RUNIT. So many people just think it’s a one off rugby tackle but nothing could be further from the truth. In rugby the odds on a full frontal collision with no avoidance by either participant are near nil.

In rugby when tackled you learn to absorb the impact thus lessening the risk, you know you’re going to be tackled and you absorb that impact but lessen it by going with the impact, this “sport” involves operating entirely against that, with both participants attempting to power through the other and no deliberate absorption of impact.

This is as dangerous a pastime as PowerSlap and is only going to see terrible injuries bestowed upon its participants, either in initial trauma from the impact or in long term form from continual exposure.

As you say however simply banning it won’t alter anything, it’ll continue albeit in an even more unregulated fashion so I am unsure as to how you’d make it safer.

Football coaches stopped doing this drill because of the injury rate.

@ngcf4238 2 months ago

$20,000 cash to risk doing this is not that much when you consider potential medical costs from complications PLUS taxes!

Rugby is well known for being safer than American football, then people decide to make an super dangerous variation

I'm Australian and have never heard of this. We play lots of football codes and I've played three of them, Rugby League, Rugby Union and Soccer. I played Union at university for one season but kept getting wrist injuries. My doctor said one day, 'Either you stop playing Union or you get another doctor. Next time this happens we'll be fusing bones together." So I stopped playing Union. In those days players with head impact just went back on the field, it was a sign of 'manliness'. It was a long time before the trouble with concussion injuries became widely known. This deliberate impact activity is even more stupid now that we know of both the short term and long term damage.

I sense adjustments to insurance resulting in immediate denial of claims related. That is crazy

@Revisit9457 2 months ago

Back in high school football, we did a drill that was basically the same: receiver blocking vs cornerback practicing for run plays. But since the drill didn't make the corner have to read run or pass first, it turned into the corner running full speed into the receiver. We called it the concussion drill. Luckily the coaches noticed it was stupid so they changed it up!

When he says human version of dog fighting, I have a hard time giving credit to anything after that

I was a "Trauma Medic" and "Police EMS" in New jersey. I work as an Ortho/X-ray Tech now. My scary thought: A person hit by a car going 20 MPH is only 14,000N. For my opinion: I still feel that we are heading towards making the movie "Idiocracy" a reality. People will eat it up. Like Juvenal said about Caesar; "Bread and Circuses" (look that up). They should force the participants to watch a video on what the long term effects look like (like the interview with the MMA Fighter 10 years after) AND if they wish to proceed, there must be some type of contract that makes the RUNIT owners responsible for their treatment. You may not be able to convince people to stop watching it. But you just may have a shot at convincing younger guys not to participate.
