PE teacher constantly mocked 'unfit' students until one outsmarted him in front of the whole class

A student (u/matijago) born with a heart condition, secretly hatched a plan to humble their PE teacher after they spent years bullying the kids for allegedly being "unfit." On October 31, 2025, years after leaving school, the student, now an adult, shared their story on Reddit.

The author was born with a congenital heart disease and had undergone surgery as a kid. Physically, they were fine, but sports never came easy to them. In fact, they were skinny, clumsy, and could never participate in outdoor activities like most kids. "I got teased and bullied and all that. Typical for a geeky kid who doesn’t excel at football," the author said. In high school, they had a PE teacher who loved making fun of kids who didn't excel in sports. Once, he asked an overweight student to do a  gymnastics jump from a trampoline, and the poor boy fell hard on his head. "I hated how he always encouraged the jock culture of making fun of 'the nerds,'" the student wrote. Their heart condition didn't allow them to do high-energy or reactive sports, and they would have had to sit down every few minutes to catch their breath. Although they deeply loved sports, it could only be the kind that supported their health condition. "I fell in love with road cycling when I first saw the Tour de France on TV. I was super skinny, couldn’t sprint, but I could climb a long mountain any day, pacing myself and blowing nearly anyone off my wheel on endurance. I got myself a road bike and never told anyone at school about my rides," they wrote. One day, the school took a sports trip to the mountains, and the PE teacher asked if anyone wanted to join him in cycling up the mountain instead of hiking. No one except the author volunteered. The PE teacher was shocked and even made vague remarks about not waiting for the student.

The teacher assumed the author wouldn't be able to climb up the mountain because he'd always seen them struggle in sports. "He also couldn’t know that was my home hill, literally starting a kilometer from my house. I did that climb 100+ times and knew it blind, knew my pacing, and while I was no Tadej Pogacar, I knew I could probably drop my PE teacher at will there," they wrote. On the day of the ride, the author came fully prepared to show the PE teacher his real place. While their overconfident teacher got a heavy mountain bike and cycled fast on the flat part, the author maintained a steady pace. Soon enough, the teacher lost his energy, and it was evident to the author. "I went only a little faster. Then a bit more. I knew after about 3km he was in the red. So I ease off, keeping him just slightly over his limit for the next half an hour. I wanted to make him suffer, but without dropping him," they said. Just as the duo reached near the top, the author went full speed ahead and left the PE teacher far behind. "I got my revenge and was very happy with myself. He said something about his heavy bike, and I kept my mouth shut. But it got better. On top, he was clearly dead. So much so, he had to vomit in the parking lot, and even if only a few classmates saw it, everyone knew," the author said. After that incident, the teacher never commented on any student or mocked them.

Meanwhile, reacting to the post, u/lumoslomas commented, "What is up with PE teachers?  I had one who absolutely hated my guts because I was excused from a lot of exercises on account of being severely asthmatic and living in the tropics (80% humidity is NOT good for my lungs). But my revenge involved me ending up in the hospital, so I think you win here." 

Similarly, u/rainbowjig said, "That’s not a teacher. That’s a bully, but fair enough, you accepted his challenge, and he lost badly. It sounds like it was a lesson learned for him."
