Ali Truwit once told a paramedic she’d never run again — now, she’s training for the New York City Marathon.

Just two years after losing her leg in a horrific shark attack, the former Yale swimmer and newly crowned Paralympic silver medalist is defying the odds.

She’s setting the bar higher once again — not on the podium, but pounding pavement on a prosthetic blade.

In doing so, she’s not just rewriting her own story, she’s using her platform to uplift others through her foundation and personal journey of resilience.

From Shark Attack Survivor to Paralympic Champion

In 2023, Ali Truwit was vacationing in Turks and Caicos with her best friend Sophie Pilkinton to celebrate their graduations from Yale and medical school, respectively. What was meant to be a post-grad getaway turned into a life-altering tragedy.

While snorkeling in shallow waters known for tourism, the two were attacked by a shark. “It got my leg in its mouth,” Truwit recalled. “The next thing I knew, it had bitten off my foot and part of my leg.”

Despite her own injuries, Pilkinton managed to apply a tourniquet around Truwit’s leg until help arrived. Truwit later underwent an above-the-knee amputation in New York City.

At 22, Truwit’s life shifted in an instant. Her dream career in consulting, a business school plan, and a five-year strategy were replaced by surgeries, prosthetics, and recovery. But that loss became the fuel for a breathtaking comeback.

Beating the Odds with Paralympic Spirit

Within a year of the attack, Truwit returned to swimming. Having previously competed at the collegiate level at Yale, she set her sights on something even bigger: the Paralympics.

In Paris 2024, just one year post-amputation, she represented Team USA in para swimming and won two silver medals — a feat few expected and one that cemented her as a symbol of mental and physical resilience.

“We are all so much stronger than we think,” she said. “When our mind tells us we have nothing left, we still have more.”

Why She’s Running a Marathon on a Prosthetic Blade

Truwit finished the Copenhagen Marathon just days before her shark attack. She thought it would be her last.

But one of her first responders, Matthew, told her differently. When she quipped from the boat, “At least I got my marathon in,” he replied, “You’ll run another one.”

And she is.

This November, she’s preparing to run the NYC Marathon on a prosthetic blade — a symbolic return to both running and the city where she underwent amputation.

Her mother, a cognitive behavioral therapist, helped her navigate this journey by teaching her to “hold the dialectic” — the idea that two truths can coexist. That mindset helped Truwit rebuild not just physically, but emotionally after trauma.

Stronger Than You Think: Her Foundation & Mission

Truwit has channeled her story into service through her nonprofit, Stronger Than You Think.

The foundation’s mission is rooted in three pillars: providing prosthetic equipment, improving water safety education, and promoting Paralympic sports.

So far, the group has provided eight prosthetics to women and girls and five water safety grants. Truwit also mentioned discussions are underway with Team USA for a potential partnership supporting the Paralympics.

“Helping is healing,” she explained. “It’s been healing for me to think I can use my story to uplift others through their challenges.”

Her Rapid Rise to Role Model Status

In a short period, Truwit went from survivor to silver medalist to publicly celebrated figure. She’s been featured in Sports Illustrated Swimsuit and signed a multi-year sponsorship deal with Nike.

Her story has reached millions, not only because of her accomplishments but because of the way she’s reframed hardship into purpose.

Training, Healing, and Choosing to Compete

Though training for a 26.2-mile race on a prosthetic blade presents physical hurdles, Truwit doesn’t wait to be told she’s ready. She acts first — driven by a lifetime habit of setting big goals and meeting them with grit.

“I have this proven track record of going for it,” she said. “I didn’t always get it on the first try, but I kept showing up.”

Her battles look different now, but her refusal to give up remains unchanged. “Today isn’t going my way, but I’ll get back up tomorrow and try again.”

And She Will Run

What started as a nightmare in ocean waters evolved into a global message of empowerment — a message Truwit channels into every stroke, every step, and now every mile she trains.

Truwit has proven she’s not just reclaiming her life, she’s rewriting what’s possible — one blade-bound stride at a time.
