A native New Yorker and the embodiment of adventure seeker, Stefanie competes and explores all over the globe. She embraces and shares her passions for adventure and ultra-endurance racing with a massive smile and all of her heart.

Stefanie has a diverse athletic background, competing and excelling in various athletics from a very young age, ranging from soccer to fencing and lacrosse. She thrives on being challenged, which led her triathlon in 2005. Stefanie spent many years in triathlon, from sprint to Ironman distances, and competed at the Long Course Age Group World Championship.

Stefanie began to flourish as an athlete upon discovering ultra-endurance sports. In 2010, she jumped at the opportunity to compete at a Peak Death Race - a race of unknown length and unknown tasks, lasting from approximately one to three days, testing athletes both physically and mentally. After becoming the overall champion 18 hours after her first Death Race, she realized that is what fueled her fire. Her love of these types of adventure competitions was apparent; she is usually the only athlete seen smiling constantly throughout races. Stefanie completed three more Death Races, lasting up to 65 hours in length, becoming the female champion twice and finishing in the top 10.

Since discovering adventure sports, Stefanie branched out into Adventure Racing and Obstacle Course Racing (OCR). Adventure Racing is a team sport, based on orienteering their way to checkpoints, either on foot, on a mountain bike, or paddling. She completed multiple races up to 72-hour adventure races, as well as the Adventure Racing World Championship, where her and her team covered about 500 miles across Wyoming in about 5 days. In recent years she has stood on multiple podiums, including a win at an A1 World Cup race in 2022.

One of her notable OCR achievements was winning the World's Toughest Mudder (WTM) in 2016 in Lake Las Vegas, Nevada. WTM is a 24-hour race, looping a 5 mile, 20 obstacle course. Stefanie dominated the women's field, completing 17 laps/85 miles and over 300 obstacles.

The trail to success has not been a linear one. Stefanie faced Lyme Disease in 2015, which she contracted while out training, but has made a full recovery. In 2017, while attempting to defend her title at WTM, she dropped from the race 30 miles in, later finding out she suffered a femoral neck stress fracture. Injuries may have kept Stefanie on the sidelines at times, but it never deterred her from racing and taking up extreme challenges. During March of 2017, she set out to do something no woman had ever done - set a Fastest Known Time (FKT) for the 46, 4,000 footer Adriondack High Peaks in the winter. Even after a historical blizzard dropped four feet of snow on the region halfway through her attempt, she continued to push, but eventually decided to stop due to the conditions. At the time it was a defeating moment, but she continues to draw from the experience to feed her zeal for adventure.

In July 2021, she set a new FKT for the 48, 4,000 footers of the White Mountains in New Hampshire. Again, she faced unpredictable weather, pushing through days of torrential rain. Trudging through flooded areas, sometimes where the water was up to her knees, she successfully completed this feat of 175 miles and 75,000 feet of vertical gain in 4 days 14 hours.

March 2022, Stefanie set out for a unique unsanctioned race with no official route known as The Speed Project Solo. With the tagline, “No Rules, No Spectators”, she raced from the Santa Monica Pier to the Las Vegas sign in just over 4 days. As documented in the film, Tenacity, as well as her own vlog, she overcame many challenges but did not back down.

All of her experiences have enabled Stefanie to inspire others to challenge themselves, whether in physical activity or everyday life. She understands the value of her experiences, both the good and the bad, and she emphasizes how mindset is a key to success. This is where she draws her mantra: "Embrace adventure and the challenges that accompany it. Smile through the adversity. Shine in the darkness. Discover yourself." She shares her wisdom to everybody she meets, from those she coaches for various adventure sports and endurance events, to packed rooms at events, and to those she meets along the trail of life.

Stefanie’s has adventured in some of the most beautiful, and brutal, landscapes across the globe. Her body has taken her to the windy mountains of Patagonia, the glaciers of Iceland, all over North America, and beyond. She is continuously in search of her next unique challenge, accompanied by her notable smile and energy.

When Stefanie is not adventuring, racing, coaching, or speaking, you may find her designing interior accessories, kicking her feet up with friends, reading, and enjoying plentiful bowls of vegan ice cream.
