Although poor weather conditions kept her from the seven-day goal of her Triple 7 Quest series, Kim Pursley has returned home after successfully running seven marathons on seven continents. Pursley, 44, of Forest Hill was 20 minutes from landing in Antarctica on Feb. 14, but her plane had to turn back and return to Chile because of poor visibility. She instead arrived in Antarctica last Wednesday, and she and her fellow runners "awoke to snow and the start of the Penguin Marathon at 6:00 a.m.," Pursley wrote in an email Tuesday to The Baltimore Sun. "The Penguin Marathon on King George Island is more or less an ultra terrain run course. It is muddy, hilly, and rocky. Very rocky." Pursley called the race the most difficult of the trip; she was suffering from an injury to her left foot, which was still swollen from a combination of travel and injury. "Every step over the jagged rocks and up the gradual hills took its toll," the former McDonogh field hockey and lacrosse player wrote. "I was also suffering from an upper respiratory cold with a terrible cough." It snowed intermittently early in the race, but Pursley said she was fortunate to avoid Antarctic winds, "which can be quite brutal." Upon finishing her last marathon, 11 days after she began the quest, Pursley left Antarctica on Thursday evening and headed back to Punta Arenas, Chile. The best part, she said, "was the journey itself … the amazing places I visited and the many talented individuals I met and befriended from around the globe." Looking ahead, Pursley said her next focus is cycling. In June 2015, she will be part of a four-member team for Race Across America, 3,000-plus-mile bike ride that starts in Oceanside, Calif., and ends in Annapolis.
