Abby Winterberger became the youngest athlete on Team USA at the 2026 Winter Olympics in Milano Cortina, Italy. At just 15 years old, she’s competing in freeski halfpipe—a sport she’s pursued for less than a decade but already mastered at elite levels.
Her path to the Olympics broke conventional routes. Most athletes reach the Games through U.S. Ski & Snowboard’s Rookie and Pro Team systems. Abby skipped all that. She qualified directly from her club team, the Olympic Valley Freestyle Freeride Team, making her achievement potentially unprecedented in American freeski halfpipe history.

Family Background: The Winterbergers
Abby’s parents, Jim and Rosemary Winterberger, describe themselves as “ski bums” who passed their passion for skiing to their children. They raised three kids in Truckee, California—a mountain town near Lake Tahoe known for producing Olympic-level winter sports athletes.
Jim Winterberger graduated from West Milford High School in New Jersey. His family has roots in the High Crest Lake community there, where his grandparents Joseph and Dorothea Winterberger were among the first settlers. Jim’s mother, Carol Giuseffi Winterberger, taught at West Milford High School, while his grandmother Doris Giuseffi taught at Paradise Knoll School.
Despite these East Coast roots, Jim and Rosemary settled in Truckee specifically for the skiing lifestyle. They introduced Abby to skis when she was barely 20 months old—so young she could barely walk steadily.
Her older brother Mack Winterberger, now 17, also competes in freeski halfpipe on the World Cup circuit. Jim describes Mack as “an absolute ripper” who faces even tougher competition in the men’s field. Mack has his own Olympic aspirations and serves as both sibling and training partner.
The family also includes younger sister Greta. All three siblings grew up skiing together, creating a household where winter sports dominated daily life.
Early Years in Truckee
Born in 2010, Abby grew up in Truckee—elevation 5,817 feet—where snow covers the ground for months each year. The region produces Olympic talent regularly due to proximity to world-class training facilities around Lake Tahoe.
She started skiing at age 2, following her older brother Mack onto the slopes. At that age, most kids are still mastering walking. Abby was learning to control speed down mountains.
By age 5, she also started gymnastics training, which she pursued seriously until age 13. Her gymnastics background gave her exceptional air awareness—the ability to know where your body is while flipping and spinning. This skill transfers directly to freeski tricks.
At age 6, she entered her first skiing competitions. She wasn’t just participating—she was chasing Mack, trying to keep up with an older brother who already showed serious talent.
The Waterslide Story
Jim Winterberger tells a story that captures Abby’s personality perfectly. During a family vacation, they stopped at a water park. Abby saw a massive slide that sent riders spinning through a giant funnel before dropping them into a pool.
She was tiny—way below the height requirement. The attendant told her no. Jim expected tears or disappointment.
Instead, “without hesitation, she dives headfirst into the funnel—without a raft,” Jim recalled. She went ripping around the bowl at ungodly speed, passing adults in rafts while the attendant stood there stunned.
That fearlessness—or calculated risk-taking, as her parents describe it—defines how she approaches skiing.
Gymnastics to Skiing Transition
From ages 5 to 13, Abby trained as a competitive gymnast. She once believed she’d make the Olympics as a gymnast, not a skier.
When COVID-19 shut down her gymnastics gym in 2020, she and Mack started building jumps in their backyard. They’d ski off homemade features repeatedly, teaching themselves tricks.
Watching the 2022 Winter Olympics in Beijing pushed her fully toward skiing. She saw athletes from the Tahoe region competing at the highest level. The Olympics suddenly felt achievable.
Her coach Cooper Davidson noticed something unique early on. “Abby’s dedication, progression and fearlessness in the pipe have been incredible to watch,” he said.
Joining Olympic Valley Freestyle Freeride Team
Abby trains with OVFree (Olympic Valley Freestyle Freeride Team), a club team with impressive alumni including Olympic gold medalists Jonny Moseley and Shannon Bahrke.
The team director spotted her on a trampoline outside the training facility after one of Mack’s sessions. He watched her flip and spin with control that most kids her age don’t have. “I want you on my team,” he told her.
OVFree allowed her to train in multiple disciplines—halfpipe, slopestyle, big air, moguls, and skiercross. This versatility made her a complete skier rather than a single-trick specialist.
Competitive Breakthrough
In 2024, at age 14, Abby dominated the USASA Open Class Nationals at Copper Mountain, Colorado. She won gold in both slopestyle and halfpipe, defending her halfpipe title from the previous year.
These weren’t small local competitions. USASA Nationals attracts the best youth freeskiers in America. Winning both events at 14 signaled she was ready for bigger stages.
World Cup Debut and Olympic Qualification
The 2025-26 season marked her first year competing on the World Cup circuit—the professional international level where Olympic qualification happens.
Despite never competing at this level before, she earned three top-10 finishes during her debut season. Her consistency in difficult weather conditions became her trademark.
The crucial moment came January 10, 2026, at the Toyota U.S. Grand Prix in Aspen, Colorado—the final Olympic qualification event. She finished sixth place, the highest finish among American women that day.
That result secured her Olympic berth. As described on her official Team USA profile, she achieved selection years ahead of the typical developmental curve.
The night before that Aspen competition, reality hit her. “I was kind of freaking out,” she admitted. “Like, ‘If I do well tomorrow, this could actually happen.’ I didn’t really believe it.”
But it did happen.
Breaking the Traditional Path
U.S. freeski sport director Skogen Sprang explained that the qualification system rewards breakthrough performances. “The door is wide open to an up-and-coming athlete who performs well against the World Cup field,” he said. “Abby capitalized on her first age-eligible year and posted some amazing results.”
Her club-level qualification represents a rare—possibly unique—achievement in U.S. freeski halfpipe history. According to NBC News coverage, she bypassed the entire traditional development structure that typically takes athletes 4-6 years to navigate.
Youngest Team USA Athlete
At 15, Abby is the youngest athlete representing the United States at the 2026 Winter Olympics across all sports. Freeskier Maggie Voisin remains the youngest American ever to qualify for Winter Olympics freestyle skiing—she was 15 at the 2014 Sochi Games. Abby is only months older but holds the distinction of being youngest overall at Milano Cortina.
She’s too young for a driver’s license in California but old enough to compete against the world’s best halfpipe skiers.

Balancing Olympic Training and Teenage Life
Abby attends school entirely remotely to accommodate year-round travel for training and competition. Her friends go to conventional in-person high school in Truckee.
She considered attending regular school but realized it would limit her skiing. “This is the life that I want to be living,” she said.
To chase snow year-round, she travels constantly between North America, Europe, and New Zealand. This schedule requires maturity beyond her years—managing training, schoolwork, and the pressure of Olympic-level competition.
The Send-Off Party
On January 27, 2026, Tahoe Sports Hub in Truckee hosted a send-off party for Abby. The venue was packed wall-to-wall with community members celebrating one of their own heading to the Olympics.
Her mother Rosemary addressed the crowd: “We always knew that she had this potential, but the fact that it’s all happening at 15 is just amazing. Being able to see our two older kids together pursuing their passion has been amazing.”
The entire family traveled to Italy to support Abby—Jim, Rosemary, Mack, and Greta all made the trip.
Olympic Performance
The 2026 Winter Olympics opened in Milano Cortina, Italy, with freestyle skiing events held in Livigno near the Swiss border. Abby competed against women she watched on TV just four years ago during the Beijing Olympics.
Competing alongside her heroes feels “surreal,” she said. These are skiers she studied, whose tricks she tried to replicate, whose careers she followed online.
She finished 18th overall in World Cup rankings and seventh in freeski halfpipe during the 2025-26 season leading into the Olympics—impressive results for someone in her first professional year.
Physical Attributes and Training
At 15, Abby still has years of physical development ahead. Her gymnastics background gave her exceptional core strength, flexibility, and air awareness that elite skiers train years to develop.
Halfpipe skiing requires explosive power for launching out of the pipe, precise body control during tricks, and the physical toughness to handle crashes at high speed.
She trains on trampolines to perfect aerial maneuvers before attempting them on snow. The progression goes: trampoline, airbag landing, snow with soft conditions, then finally competition-level performance.
“She says, ‘I trust my training. I trust my coaches, and I know I’m ready,'” Rosemary explained. “We don’t think she’s fearless. We think she absolutely has fear. She definitely gets scared, but she’s calculated.”
