You see a teenager standing on the starting platform, bright lights reflecting off the water below. She’s small—only five-foot-two—but there’s a mechanical device on her arm that catches the light. That’s a Dexcom. For most people, American Ninja Warrior is a test of grip strength and nerves. For Katie Bone, it’s a constant, high-stakes math equation involving insulin units, blood glucose levels, and sheer adrenaline.
Honestly, we see a lot of "inspirational" stories on TV. But Katie Bone isn't just a feel-good segment. She's a legitimately elite athlete who has fundamentally changed what people think is possible for Type 1 diabetics. She didn't just participate; she won.
The Night Katie Bone American Ninja Warrior History Was Made
In Season 14, something shifted. Bone wasn't just another rookie teen. She was the first woman to clear Stage 2 of the National Finals in Las Vegas—a feat that only a handful of women have ever achieved in the show's history. When she hit that buzzer in the Women's Championship, it wasn't just a victory for her. It was a roar for every kid who has ever been told to "take it easy" because of a medical condition.
She was 17. A high school junior. While most kids her age were worrying about prom or SATs, she was navigating the Falling Shelves and Hornet's Nest.
The T1D Factor: More Than Just an Obstacle
Living with Type 1 diabetes (T1D) is basically a full-time job without a lunch break. Katie was diagnosed at age 11. Her first question to the doctor? "When can I climb again?" That tells you everything you need to know about her.
On the course, she wears an Omnipod and a Dexcom. These aren't just gadgets; they're her lifeline. During the filming of the semi-finals, she actually had a significant blood sugar drop right when it was time for her to run. Imagine your body literally running out of fuel while you're expected to hang from your fingertips thirty feet in the air.

- The Tech: She uses a continuous glucose monitor (CGM) that syncs to her phone.
- The Support: Her boyfriend, fellow ninja Kaden Lebsack, and her family monitor her levels on their phones while she's competing.
- The Motto: "I don't need easy; I just need possible."
It’s easy to forget that while she’s swinging on the Fly Hooks, she’s also calculating how the adrenaline of a national broadcast is going to spike her glucose. Adrenaline usually makes blood sugar rise, but the intense physical exertion of the obstacles can make it crash. Balancing that is like trying to walk a tightrope in a hurricane.
The Injury That Sidelined a Champion
After the high of winning the Women's Championship, disaster struck. It wasn't a failed obstacle on TV. It was during the USA Climbing National Team Trials. Katie tore her ACL and her meniscus.
She missed Season 15. She missed Season 16.
For two years, the "Ninja Prodigy" was in the lab, so to speak. Rehab is a grind. It’s boring, painful, and mentally exhausting. She had three surgeries. There were times, she’s admitted, where she wanted to walk away from both ninja and her first love, competitive rock climbing.
But she didn't.
The Season 17 Comeback
Watching Katie Bone return for Season 17 was one of those "get the tissues" moments. She didn't come back as a shadow of herself. She came back with a reconstructed knee and something to prove.
In the qualifiers, she hit the buzzer. The emotion was raw. You could see the weight of those two years of rehab falling off her shoulders the second her hand slammed that red button. Even though she eventually went out on the Log Runner in the semi-finals—a heartbreak caused by an overshot step—her presence alone was a statement.
Beyond the Course: The Olympic Dream
Don't pigeonhole her as just a "ninja." Katie is a world-class speed climber. She’s currently training for the 2028 Olympics in Los Angeles. Speed climbing is a whole different beast. It’s about explosive, vertical movement where every millisecond counts.
She has competed in China, Europe, and all over the U.S. In 2024 alone, she was hitting IFSC World Cups and placing in the top 20 globally.
Real-World Advocacy
Katie Bone doesn't just talk about diabetes in interviews; she goes to Washington. In 2025, she testified before the Senate Appropriations Committee to advocate for the Special Diabetes Program. She’s used her American Ninja Warrior fame to push for research funding.
Most people see the win. They don't see:
- The 100+ daily decisions about carbs and insulin.
- The alarms going off at 3:00 AM because of a "low."
- Carrying her own specialized food across three continents for competitions.
- The frustration of a "high" blood sugar day making her feel sluggish during a 7-hour training session.
What You Can Learn from Katie’s Journey
If you’re an athlete dealing with a chronic illness, or just someone facing a massive setback, Katie’s approach is a blueprint.
Accept the "How," not the "No"
She often talks about the "Yes, but how" mentality. It’s not about whether you can do it; it’s about figuring out the specific logistics required for you to do it.
Find Your Crew
She credits her boyfriend Kaden and her climbing community for keeping her sane during the knee surgeries. You can't be a ninja alone.
Control the Controllables
Diabetes is unpredictable. Knees are unpredictable. Katie focuses on her sleep, her warmup, and her nutrition. Everything else? You just handle it as it comes.
