Sara Jenner achieved a historic milestone by becoming the first American woman to ski solo and unsupported to the South Pole, completing the grueling 57-day journey across Antarctica’s harsh terrain.
Overcoming Fear and Inexperience
Jenner started as a novice skier just three years before the expedition. Living as a 36-year-old single woman in Massachusetts, she drew inspiration from Preet Chandi’s similar feat as the first woman of color to accomplish the challenge. Chandi’s story resonated because she also learned to ski after committing to the goal.
“Fear wasn’t a good enough excuse,” Jenner states, highlighting her decision to push past doubts about failure and survival. She began training after searching online for polar expedition preparation, joining a trip with Polar Explorers. Guides there encouraged her, affirming she could succeed with dedicated effort.
Intensive Global Training Regimen
For over two years, Jenner trained five to six days a week, running, weightlifting, and dragging tires to mimic sled pulling. Her coach, Jon Fearne of E3 Coach, emphasized consistency. She traveled to Nepal, Greenland, Norway, and Minnesota, where she once fell through ice—a terrifying lesson in resilience.
In the final year, she gained 25 pounds of muscle and fat to endure the calorie deficit, consuming 5,000 calories daily while burning nearly 7,000. She completed the expedition 25 pounds lighter but healthy. The total cost exceeded $120,000, funded through savings amid intense stress.
Launch into Isolation
In November 2025, Jenner flew to Union Glacier Camp, 700 miles from the Pole. A short flight dropped her at the ice edge, where the plane departed, leaving her alone. Surprisingly, fear did not overwhelm her. She pulled a 250-pound sled carrying all gear and dehydrated meals, melting snow for water on a camping stove.
She named her sleds after her dream meal—roast chicken and green beans—and chatted aloud with “Auntie Arctica,” the vast landscape, even recounting past relationships to pass time.
Brutal Challenges on the Ice
Day 45 brought despair amid whiteouts, high winds, and snow ridges taller than her 5-foot-5 frame. Temperatures dropped below -20°C, limiting breaks to avoid frostbite. Extreme chafing and her menstrual cycle added misery; with only two pairs of underwear, she managed with a menstrual cup in her tent’s vestibule.
Polar thigh—a common cold injury causing rashes and potential lesions—affected her legs early, treated with dressings. Weekly doctor calls provided guidance. Days 20 to 30, including her birthday, tested her mentally with endless whiteouts and no horizon. She forced daily positive notes in Garmin updates to loved ones, boosting her spirits.
Her sleeping bag proved the most vital item, offering warmth and security in the tent that served as home.
Triumph at the Pole
In the final week, Jenner sensed support from family, friends, and online followers. The hours before arrival held a thrilling anticipation of success. “Without question, the hardest thing I’ve ever done,” she reflects on the physical and mental toll of daily skiing while battling tears.
Jenner discovered untapped inner strength, proving that starting imperfectly and scared leads to extraordinary achievements. She now writes a book about the experience, transforming a simple decision to overcome fear into polar history.
