Park City resident Rob Lea has achieved a unprecedented feat in endurance athletics, becoming the first person to complete the 'Double Seven' challenge by summiting the highest peak on each continent and swimming the world’s seven most iconic open-water channels. The nearly two-decade journey concluded on June 30 when Lea successfully crossed Japan’s Tsugaru Strait.
A Seventeen Year Journey concludes
The monumental undertaking, which Lea described as both exciting and bittersweet, began 17 years ago. His quest for global extremes officially commenced in 2009 when he summited Aconcagua, the highest peak in South America. A decade after that initial climb, Lea completed the first of his seven required open-water channel swims.
Speaking on KPCW’s 'Local News Hour' on July 6, Lea noted that while finishing the checklist is a major milestone, he will miss the anticipation of future goals. He described the project as a way to travel the world and experience diverse cultures through extreme adventure.
From injury to world records
Lea’s inspiration for the challenge was born from a period of physical recovery. While sitting at a doctor's table recovering from an ankle injury, the lifelong swimmer and triathlete decided he would attempt to swim the English Channel. This decision eventually led him to research the intersection of mountaineering and open-water swimming.
During his research, Lea discovered that only nine individuals had ever completed both an English Channel swim and a climb of Mount Everest. This discovery motivated him to pursue the 'Peak and Pond Challenge,' aiming to accomplish both feats within a single calendar year. In that same ambitious year, he also utilized his triathlon background to cycle across the United States.
Influences and elite ranks
Lea credited much of his ambition to his wife, Caroline Gleich, a professional skier and mountaineer. Gleich, who notably became the first woman and only the fourth skier to complete all 90 lines in the Chuting Gallery of the Wasatch Mountains, served as a primary influence on his ability to 'dream big.'
While Lea's achievements are historic, he is part of a small group of elite endurance athletes. Mountaineering experts estimate that fewer than 1,000 people have successfully completed the Seven Summits challenge, and Lea believes he is only the 46th person to complete the Ocean Seven swims.
Extreme physical tolls
The path to the world record was marked by extreme physical danger and logistical difficulty. Lea identified his swim from Molokai to Oahu in Hawaii as his most perilous ordeal. After a 14-hour effort, the swim left him hospitalized with swimming-induced pulmonary edema (SIPE), an experience where he believed he was drowning and feared he would not reach the shoreline.
While the swims presented immediate life-threatening risks, Lea noted that recovering from Mount Everest was more physically taxing. He described the recovery from the 'death zone' as a period where the body is essentially consuming itself, requiring weeks of intense nourishment to feel normal again.
The final crossing
The final leg of the challenge, crossing Japan's Tsugaru Strait on June 30, presented a unique logistical hurdle. It was the only one of his 14 major climbs and channel crossings that he failed to complete on his first attempt due to the unpredictable nature of tides, currents, and weather.
Despite the conclusion of the 'Double Seven,' Lea is not stepping away from endurance competition. He and Gleich are currently preparing for the upcoming TCS New York City Marathon, scheduled for November 1, 2026.
Looking toward New York
The TCS New York City Marathon, which serves as the next milestone for Lea, is one of the world's most prominent running events. The 2026 marathon is set to take place on November 1, following a legacy of massive participation, including 59,226 finishers in 2025.
As part of the broader running community, the event features participants from over 130 countries and serves as a platform for significant charitable contributions, with NYRR reporting $680 million raised for charity since 2006.
