ANCHORAGE, Alaska (AP) -- Much of the start of the world's most famous sled dog race is covered in barren gravel, forcing Iditarod organizers to move the start further north where there is snow and ice.
A weather pattern that buried the eastern U.S. in snow has left Alaska fairly warm and relatively snow-free this winter, especially south of the Alaska Range.
"If I have one more person say to me to move the Iditarod to Boston, I'm going to shake my head," said race director Mark Nordman.
The Iditarod Trail Sled Dog Race starts Saturday with a ceremonial run through Anchorage. But the official start two days later has been moved 225 miles (360 kilometers) north, over the Alaska Range, to Fairbanks to avoid the area that left many mushers bruised and bloodied last year. Iditarod officials said the conditions are worse this year.
The race's chief executive officer, Stan Hooley, called the conditions "pretty miserable." And last year was no picnic.
One musher last year was taken out by a rescue helicopter after making it through the Dalzell Gorge only to hit his head on a tree stump in the Farewell Burn. Knocked unconscious for at least an hour, Scott Janssen got back on the trail after waking up. But shortly after, he broke his ankle while walking on ice trying to corral a loose dog.
"As an outdoorsman, to have to be rescued from the trail isn't a wonderful thing," Janssen said.
This year's race will feature 78 mushers, including six former champions and 20 rookies. The winner is expected in Nome in about 10 days.
Alaskans can thank the jet stream, which has been delivering warm air from the Pacific, said Dave Snider, a meteorologist with the National Weather Service in Anchorage.
"That position of the jet has been pretty stagnant, or at least in the general same position for a long period of time. While that's allowing a lot of cold air to flow out of the Arctic into the Midwest and the eastern seaboard, we're locked into the warmer part of that pattern, and we've continued to see those warm pushes for a fairly long period over the winter," he said.
Anchorage gets about 60 inches (150 centimeters) of snow in a normal year; this year only about 20 inches (50 centimeters) have fallen.
The new route, which puts mushers on river ice for about 600 miles, could level the playing field.
"Nobody has a plan," Nordman said. "You're not going to be stopping and putting your snow hook into the same tree you had the last 20 years. It's a whole new ballgame."
Brent Sass of Eureka, Alaska, is running his third Iditarod, and is coming off a win in last month's 1,000-mile (1,600-kilometer) Yukon Quest International Sled Dog Race.
"It doesn't hurt a guy like me who has only run the race a couple of times," he said of the route change. "For the guys that have run the race 20 times, it's not just the normal routine so it might throw them off a little bit."
Among the veterans in this year's race is the defending champion, Dallas Seavey, and the 2014 bizarre finish will be remembered as much as the poor trail conditions.
A sudden blizzard blew four-time champion and race leader Jeff King out of the race when he was about 25 miles (40 kilometers) from the finish line of the nearly 1,000-mile race.
Then Aliy Zirkle, who was solidly in second place, waited out the storm at the last checkpoint, 22 miles (35 kilometers) from Nome, for two hours, 38 minutes. She got back on the trail when Seavey blew through the checkpoint, but lost the race by two minutes, 22 seconds. It was her third straight runner-up finish with no wins.
The route change eliminates the mountainous terrain and treacherous gorge, but it could present mushers with a whole new set of problems with a flat trail on unpredictable river ice. Plus, because it's an entirely new route, mushers say they can't rely much on information, even something as simple as the mileage between village checkpoints, provided by Iditarod officials.
By removing the Alaska Range, mushers may assume it will be a very fast race, Seavey said.
"Just because it's a flat trail does not mean your dogs can all of a sudden do 10 times what they've been able to do in the past," said Seavey, a two-time champion. "I feel that is a trap that will catch a lot of people."
"In the end, this race will not be won on tricks or gimmicks. It will be won on good dogmanship," he said.
