ANCHORAGE, Alaska (AP) - A Norwegian musher has seized the lead early on the fourth day of the Iditarod Trail Sled Dog Race.

Official standings Wednesday show Joar Leifseth Ulsom as the first musher into Ophir (OH-fur).

The checkpoint 352 miles (566 kilometers) from the race start. Ulsom stayed for 10 minutes and left shortly before 5 a.m.

Ulsom is from Mo I Rana in Norway. He was the 2013 Iditarod Rookie of the Year.

Hugh Neff of Tok is in second place on the trail to Ophir and reigning champion Mitch Seavey is in third.

Sixty-seven teams began the race Sunday in Willow.

The winner will take about nine days to travel 1,000 miles (1,600 kilometers) over trails and frozen rivers to reach Nome on Alaska's west coast.
