ANCHORAGE, Alaska -- Mushers and their dogs took a leisurely jaunt through Anchorage on Saturday in the ceremonial start of Alaska's Iditarod Trail Sled Dog Race.The 1,000-mile race kicked off in a festive mood as 66 teams posed with fans and sailed their sleds 11 miles on streets covered with trucked-in snow. Each sled carried an Iditarider, a fan who won the short ride at auction."Today is fun, with a capital F," said smiling veteran musher Aliy Zirkle, the runner-up in last year's race. "If you don't have a good time on Saturday with your dogs and all these fans, you're not in the right sport."The event comes ahead of the real, competitive start of the race Sunday in Willow, 50 miles to the north. This is when teams leave the big crowds behind for remote terrain shared mostly with their dogs."Today we have fun. Tomorrow we're serious," said defending champion Dallas Seavey of Willow.From Willow, where the race clock starts ticking, mushers and their dog teams will begin making their way through unforgiving wilderness toward the finish line in the old frontier town of Nome on Alaska's western coast. Before reaching their destination, the teams will cross mountains, frozen rivers and forests before hitting the wind-pummeled coast.They'll sign in at village checkpoints, sometimes stopping for mandatory layovers.The winner will get a new truck and $50,400. The rest of the $600,000 purse will be split among the next 29 mushers to cross the finish line.The 41st running of the race features six past Iditarod winners, including Seavey and his father, Mitch Seavey. Dallas Seavey also is among six past winners of the 1,000-mile Yukon Quest International Sled Dog Race, held just weeks before the Iditarod.Lance Mackey of Fairbanks -- the only musher to ever win both races the same year -- scratched from the Quest in February because of a team of ailing dogs. He is going for a fifth win in the Iditarod, this time taking mostly young dogs and only four veterans from the Quest.
