ANCHORAGE, Alaska--The 2004 winner of Alaska’s famous 1,000-mile sled-dog race, the Iditarod, won again at age 53 to become the oldest champion in 2013, a year after his son became the youngest winner.

Mitch Seavey got his dogs to the finishing line first in 9 days, 7 hours, 39 minutes and 56 seconds. His son, Dallas Seavey, now 26, ended up ranking fourth, behind the older competitor, 43-year-old Aliy Zirkle, who followed four-time champion Jeff King, now 57.

Mitch Seavey, who lives in Seward, Alaska, operates a seasonal sled-dog touring business. The race was Mitch Seavey’s 20th Iditarod.

This year’s contest was marked by unusual conditions and unseasonable rain in the northern part of the trail, and conditions that Seavey said helped his team. “It seems like the tougher it is, the better we can do.”

He also thought highly of Zirkle, a New England immigrant（移民）who now lives in Two Rivers, Alaska. “She’s a great musher（赶狗拉雪橇的人）, and she’s going to win the Iditarod sometime, and probably more than once. We just had a little more energy, I think.” Zirkle, one of the most popular mushers, was greeted by shouts of “Aliy, Ally” from the fans as she drove her dog team approaching the finishing line on Nome’s Front Street. “I am pretty happy to be here,” she said. “I was going for it.”

The Iditarod Trail Sled Dog Race is one of the few major U. S. sports events in which men and women compete on an equal footing. The name “Iditarod” dates from a local Athabascan term meaning “a far, distant place”. Youthful mushers in the race may have some physical advantages--they can do some things more easily. But more importantly, winning the race needs the experience in dog race.

The year’s event started on Saturday, March 2 with a ceremonial nm in Anchorage. Of the 66 mushers who started the race, 10 had dropped out of competition as of Tuesday night. For his victory, Mitch Seavey will take home $50,400 and a new truck.
