Anchorage, Alaska (CNN) - Despite near record snowfall, the 40th running of the Iditarod sled dog race kicked off in Anchorage on Saturday. However, only hours after the ceremonial start of the race, Iditarod officials announced the trail's course was being altered due to worsening weather conditions.
Sixty-six mushers entered this year's race, a true test of human and canine endurance. The contest requires each musher and dog sled team to traverse almost 1,000 miles across Alaska's notorious winter terrain - between Anchorage and Nome on the Bering Sea coast.
This year, Anchorage has already doubled its usual snowfall with approximately 120 inches - 10 feet of snow - and is approachingĀ the near 133-inch record set in 1954. The deep snow couldĀ be a major factor in the Iditarod, as weather conditions affect the dogs' physical performance and increase the threat of dangerous moose encounters on the trail.Ā Several Iditarod mushers have already reported run-ins with winter-weary moose during training runs through interior Alaska.
Hours after Saturday morning's ceremonial start, race director Mark Nordman announced trail breakers had become more concerned over a previously planned reroute in a critical part of the 2012 trail. Citing high wind and new snow totals, Nordman broke last-minute news of the change to mushers and fans.
"As trail conditions are constantly affected by changes in weather," the Iditarod Trail Committee "will consistently evaluate available options with the goal of providing the best possible trail," said Nordman - meaning the dangerous, highly feared and ironically named "Happy Steps" would officially be back in the 2012 race route.
Veteran musher and 2012 Yukon Quest champion Hugh Neff of Tok, Alaska, is no stranger to harsh trail conditions: HeĀ lost one of his own race dogs to overflow ice and suffered severe frostbite during previous competitions. "You really have to respect Mother Nature, and Lord knows, sheās been beating up on me over the years. So, we just have got to take care of the dogs and keep an even keel," Neff said.
