For the second time in three years, Norway's Robert Sorlie delivered a brave performance to win sled-dog racing's toughest contest—the Iditarod. The 47-year-old firefighter crossed the finish line in Nome, Alaska, at 8:39 a.m. local time Wednesday morning.

"It feels good to be here," he declared, after passing the finish line. "I'm ready for breakfast."

Frosty temperatures, rough land, and exhaustion couldn't break the musher （赶狗拉雪撬的人）, who completed the race in 9 days, 18 hours, 39 minutes, and 31 seconds. Runner-up Ed Iten finished 34 minutes later, and defending champ Mitch Seavey finished third.

Sorlie took his first lead at the 365-mile mark, but fell into second place halfway through the race. With 500 miles to go, he regained the lead for good.

Iditarod officials rewarded Sorlie with a generous prize of $72,066 and a new truck. But even more exciting for the winner was the historic nature of his ride. By winning this year's race, Sorlie joins a best group of mushers, becoming only the sixth person to win the Iditarod more than once.

After winning several major long-distance races in Europe, Sorlie made his Iditarod first appearance in 2002, finishing in ninth place. A year later, he returned to take on the Alaskan wilderness once again, and won.
