You’ve probably seen the photo. It’s grainy, black and white, and looks like a chaotic scuffle on a suburban road. A man in a suit is lunging at a young woman in a baggy sweatshirt, trying to rip a paper number off her chest. People usually think they know the story of Boston Marathon Kathrine Switzer, but the reality is way messier—and honestly, way more badass—than a single snapshot can capture.
In 1967, women weren't "allowed" to run the Boston Marathon. It wasn't even that there was a specific rule saying "No Girls Allowed." It was just understood. People genuinely believed that if a woman ran 26.2 miles, her uterus might literally fall out. I'm not even kidding. That was the medical "expertise" of the era.
The Myth of the Secret Entry
One thing people get wrong all the time is the idea that Kathrine Switzer "snuck" into the race. She didn't. She wasn't wearing a disguise or a fake mustache.
She was a 20-year-old journalism student at Syracuse University training with the men’s cross-country team. Her coach, Arnie Briggs, was a veteran of 15 Boston Marathons. When she told him she wanted to run it, he didn't believe a "fragile woman" could do it. But he made her a deal: "If you prove to me you can run the distance in practice, I’ll be the first to take you to Boston."
She didn't just run 26 miles in practice. She ran 31.
When it came time to sign up, she checked the rulebook. There was no mention of gender. She signed her entry form "K.V. Switzer," which is how she signed all her articles for the university paper. It wasn't a trick to hide her identity; it was just her signature. The race officials assumed K.V. stood for a man, and they sent her bib number 261 in the mail.
That Moment at Mile Four
The morning of April 19, 1967, was miserable. It was snowing and sleeting. Kathrine showed up in a heavy grey sweatsuit and put on some lipstick because, as she later said, she wanted to look like a woman. She wasn't trying to hide.

About four miles into the race, the press bus caught up to her group. The journalists realized a woman was running with an official bib, and they started freaking out. That’s when Jock Semple, the race co-director, lost his mind.
Semple was a fiery Scotsman who took the rules of the Boston Athletic Association (BAA) very seriously. He jumped off the bus, ran after Kathrine, and grabbed her shoulders. He screamed, "Get the hell out of my race and give me those numbers!"
He actually managed to rip one corner of her bib.
What happens next is the stuff of sports legend. Kathrine’s boyfriend at the time, Tom Miller—an ex-football player and nationally ranked hammer thrower who weighed about 235 pounds—was running right next to her. Miller leveled Semple with a massive shoulder block, sending the race official flying into the ditch.
Arnie Briggs, her coach, yelled at her to "Run like hell!"
And she did.

Beyond the "Boston Incident"
It’s easy to focus on the drama, but the aftermath is what actually changed the world. After Semple was shoved aside, the press truck followed Kathrine for miles. Reporters were shouting at her, asking what she was trying to prove and when she was going to quit.
She felt humiliated. Shaken.
But as she ran, the anger turned into a realization. She realized that if she didn't finish, people would say, "See? We told you women couldn't do it." She had to finish on her hands and knees if necessary.
She crossed the line in about 4 hours and 20 minutes.
The BAA promptly disqualified her and expelled her from the Amateur Athletic Union. They cited rules that didn't technically exist at the time of her entry, like the claim that women weren't allowed to race more than 1.5 miles.
The Long Road to 1972
It took five more years of lobbying and "unofficial" running by women like Bobbi Gibb (who actually beat Kathrine in 1967 but ran without a bib) before the Boston Marathon finally opened its doors to women in 1972.

Kathrine didn't stop at being a pioneer. She became an elite athlete. In 1974, she won the New York City Marathon. In 1975, she returned to Boston and ran a personal best of 2:51:37—finishing second.
She also did something most people wouldn't: she became friends with Jock Semple.
Years later, they reconciled. Semple eventually admitted he was wrong, and they became close. Before he died in 1988, she even visited him in the hospital. It’s a wild reminder that even the biggest antagonists in history can change their minds when presented with undeniable proof of human capability.
Why Bib 261 Still Matters
In 2017, for the 50th anniversary of her historic run, Kathrine Switzer ran the Boston Marathon again at age 70. She wore the same number: 261.
She finished in 4:44:31. That’s only about 24 minutes slower than her time as a 20-year-old.
Today, her organization, 261 Fearless, uses that iconic number to empower women through running clubs globally. The number 261 was officially retired by the BAA after her 2017 run—a pretty massive shift from the day they tried to rip it off her back.
Actionable Takeaways for Runners and History Buffs
If you're inspired by the story of Boston Marathon Kathrine Switzer, here’s how to apply that "261 Fearless" mindset to your own life or training:
- Don't wait for permission. If the "rules" are based on outdated assumptions rather than actual logic, find a way to test the boundaries. Kathrine checked the rulebook and found it didn't explicitly forbid her—so she went for it.
- Proof is the best argument. People told Kathrine women weren't physically capable of the distance. She didn't just argue with them; she ran 31 miles in practice to prove it to herself first, then 26.2 to prove it to the world.
- Finish what you start. The "Boston Incident" could have ended her career at mile four. By choosing to finish, she turned a physical assault into a global movement. When things go sideways in a race or a project, the act of finishing is often more important than the time on the clock.
- Support the legacy. Look into local chapters of 261 Fearless or other women's running groups. The barrier to entry is gone, but the community of empowerment remains the core of what Switzer started.
The story of the 1967 Boston Marathon isn't just about a girl who wanted to run. It's about what happens when one person decides that "that's just the way it's always been" isn't a good enough reason to stop.
