Ten days before the shark attack, Ali Truwit ran her first marathon. It was Mother’s Day 2023, in Copenhagen, alongside her mom.
Two and a half years later, on a bright November morning, she crossed the finish line of the New York City Marathon on a carbon-fibre running blade.
In between, she survived, rebuilt, and became one of the most quietly inspiring endurance athletes in the world.
In May 2023, Truwit was on a graduation trip to Turks and Caicos with her former Yale teammate Sophie Pilkinton. She had just captained the Yale swim team.
he two were snorkelling when a shark clamped onto her left leg.
They swam roughly 55 metres back to their boat. Pilkinton, a medical student at the time, applied a tourniquet that stemmed the bleeding and saved Truwit’s life.
Doctors amputated her lower left leg on her 23rd birthday.
In a hospital bed, she joked to a first responder that at least she had gotten her marathon in first.
The responder’s reply became the seed of everything that followed: "You’ll run another one."
Weeks after the amputation, Truwit was already balancing on a prosthetic.
Within months, she was back in the pool, learning to swim with a body that felt like a stranger’s.
The sound of water triggered flashbacks. She kept going anyway.
At the Paris 2024 Paralympic Games, less than 16 months after the attack, she stood on the podium with a silver and a bronze medal around her neck.
She dedicated the moment to the people who saved her.
Her full journey is captured in a detailed profile on Team USA, which traces the recovery, the training, and the mindset shift that carried her through.
The 2025 New York City Marathon was not just another race.
It was the promise she made to herself in the hospital, the same city where her amputation happened.
On 2 November 2025, Truwit lined up in Staten Island with a team of 13 family members and friends, all wearing blue T-shirts stamped with the name of her foundation, Stronger Than You Think.
Pilkinton, the friend who saved her life, was in the group.
They ran the entire 26.2 miles together. When Truwit finally crossed the finish line, she was, in her own words, "over the moon."
A running blade is not a shoe. It is a carbon-fibre spring that stores and releases energy with every stride.
It also demands more from the amputee’s remaining muscles, hips, and core than an intact leg does.
Truwit trained with the same discipline she had used for the Paralympics: structured, patient, mentally robust.
Her preparation looked a lot like any elite runner’s comeback plan, just with the added variable of learning to run again from scratch on a prosthetic.
For any runner rebuilding after a serious setback, the principles look surprisingly similar.
A structured, patient return is the foundation, as covered in this guide on returning to running training after an injury.
One line from Truwit captures her approach as well as anything: "If you can see it, you can be it."
She has been open about the fact that she is still healing. "Grief comes in waves," she told CNN.
She has spoken candidly about making significant progress on the healing journey while acknowledging there is still road ahead.
Her honesty is part of what makes her story land. She is not selling a fairy-tale comeback.
She is showing what it looks like to keep moving through the hard days, one training session at a time.
If you need a mental reset before a big session or a long run, this collection of running quotes to motivate and inspire your next run is a good place to start.
Most runners will never face a shark attack. Most will, at some point, face an injury, a setback, or a season where the sport feels lost to them.
Truwit’s comeback is a reminder that the path back is rarely linear, and that support systems matter more than motivation.
She ran New York with 13 people who love her, including the friend who applied the tourniquet. That is not a coincidence.
Every long recovery is easier when it stops being a solo project.
If you are grinding through a rehab, a low patch, or a hard training block, telling one or two people about it is often the difference between finishing and quitting.
Truwit is not the runner she was before the attack.
She is a different runner, on a blade, with a foundation, a book deal, and a Paralympic medal. She did not return to her old life. She built a new one.
That reframe matters after any setback.
The goal is rarely to become exactly who you were. The goal is to become someone strong enough for the life ahead.
Truwit’s nonprofit, Stronger Than You Think, was born out of what she learned during her own recovery.
Running blades and sports prosthetics can cost between a few thousand dollars and $70,000, and insurance rarely covers them.
Her foundation provides financial assistance for prosthetics, funds water-safety lessons, and supports the Paralympic movement.
To date, it has delivered more than 11 prosthetics, nearly $200,000 in direct support, and over 4,000 hours of lessons to more than 700 young people.
That impact would matter even without a marathon story attached. With one, it lands even harder.
Ali Truwit lost her lower leg, her sense of safety in the water, and part of the identity she had built around swimming.
Two and a half years later, she is a two-time Paralympic medallist, a nonprofit founder, and a New York City Marathon finisher on a running blade.
Her next goal is the 2028 Paralympics in Los Angeles, on home soil.
If her recent track record is any indication, that is not a stretch, it is a matter of time.
Some athletes make you rethink what a good week of training looks like.
Ruwit makes you rethink what a life looks like. Stronger than you think turns out to be more than a T-shirt slogan.
