At South Beach Prosthetics, we believe every prosthetic tells a story of resilience, courage, and renewed possibility. Few stories embody that belief as powerfully as that of Jacky Hunt-Broersma—an ultrarunner, cancer survivor, author, and mother whose determination continues to redefine what’s possible.
From Cancer Diagnosis to Competitive Running
Jacky’s journey began in 2001 when she was diagnosed with Ewing sarcoma, a rare bone-associated cancer. At age 26, she underwent amputation of her left leg—an experience that marked both an ending and a beginning.
Despite the challenges that followed, Jacky discovered a path forward through running. She began her running journey in 2016, quickly progressing from local 5k races to ultramarathons—and proving her own doubts—and others’—wrong along the way.
Redefining Limits with Every Mile
Jacky has shattered records—and expectations—through unforgettable feats of endurance:
- She became the first amputee to complete the TransRockies Mountain Stage Race in Colorado, a grueling multi-day, high-altitude trail event.
- In 2020, amid pandemic disruptions, she ran 100 miles on a treadmill in under 24 hours, setting a new record among amputee athletes.
- Her most widely recognized achievement came in April 2022 when she completed 104 marathons in 104 consecutive days, including the Boston Marathon in its inaugural para-athletics division—raising over $192,000 for Amputee Blade Runners along the way.
- More recently, in March 2025, Jacky became the first amputee to run The Speed Project solo, a demanding 300+ mile route from Los Angeles to Las Vegas across desert terrain.
Each achievement spotlights not just physical grit, but a remarkable mental strength—and a commitment to empowering others.
More Than Miles: Inspiring Adaptive Sports
Beyond her racing accomplishments, Jacky is a voice for inclusion and hope. She’s authored a children’s book, Emma’s Brave Steps, and frequently speaks at schools and events, encouraging others—especially young amputees—to push beyond limitations.
She also shares candid accounts of the unique challenges of running on a prosthetic—including managing liner fit, blisters, tread wear, and equipment failures mid-race. Her transparency has helped others better understand what adaptive athletes navigate with strength and resourcefulness.
