Dynasty: Father, son become back-to-back Iditarod champions

A 53-year old man became the oldest-ever winner of Alaska's 1,000-mile (1,600-kilometer) Iditarod dog sled contest, one year after his son became the famed "mush dog" race's youngest champion.

Mitch Seavey, from the town of Seward, Alaska, was first person to cross the finish line late Tuesday at 10:39 pm Alaska Time, to the cheers of thousands of fans who lined the streets of Nome.

His son Dallas, who was just 25 when he won the race last year, was a contestant in this year's race as well.

It was Mitch Seavey's second Iditarod championship; he won his first in 2004.

Seavey covered the grueling race trail in nine days, seven hours, 39 minutes and 56 seconds. The previous oldest winner, four-time champion Jeff King, was 50 years old when he won his last Iditarod.

Second place finisher Aliy Zirkle, who was last year's runner up, failed in her bid to become just the third woman to win an Iditarod.

It was the 41st running of the iconic mush-dog race, which on its final stage covered 49 miles (78 kilometers) of challenging terrain, including miles of rolling hills.

Organizers said early Wednesday that the race was not yet over and that it could take several days for the remaining mushers to finish the demanding trek into Nome.
