Hailey Danisewicz, a dedicated athlete, has been making waves in the world of Para triathlon since her first race in July 2011 in Chicago, IL, USA. She recalls, "Crossing the finish line of that first triathlon fundamentally changed how I saw myself. Up to that point, I identified as a cancer survivor and an amputee. In that first race, I became a triathlete." This pivotal moment set her on a path to numerous achievements.

| Season | Event | Rank |
|---|---|---|
| 2020 | PTS2 | S Silver |
| 2016 | Women's PT2 | S Silver |
Since 2018, Danisewicz has been a member of the US national Para triathlon resident team in Colorado Springs, CO. She says, "A team of us have been training together since 2018. Honestly, the resident team has been a game changer for me." Her coach, Derick Williamson, has played a significant role in her development.
One of Danisewicz's most memorable achievements is winning silver in the women's PT2 event at the 2016 Paralympic Games in Rio de Janeiro. In 2015, she was named Female Para Triathlete of the Year by USA Triathlon. These accolades highlight her dedication and skill in the sport.
In October 2022, Danisewicz sustained a concussion in a bike crash. Despite this setback, she continued to push forward. In 2023, she returned to using a fixed blade prosthetic after experimenting with a knee joint since 2019. She explains, "The problem is the lab isn't the real world... In my very first run back [with the fixed blade], I felt an effortlessness I never felt with the knee."
Danisewicz's philosophy revolves around taking calculated risks. She believes that practising risk-taking in safe environments helps manage discomfort when it matters most. Her influences include Coach Keri Serota and US Para triathlete Melissa Stockwell.
Looking ahead, Danisewicz aims to win gold at the 2024 Paralympic Games in Paris. This goal drives her daily training and commitment to the sport. Her journey from a novice triathlete to an elite competitor serves as an inspiration to many.
Danisewicz's story is one of resilience and determination. From overcoming injuries to adapting new prosthetics, she continues to strive for excellence. As she prepares for Paris 2024, her focus remains unwavering on achieving her ultimate goal.
