The top five mushers in the Iditarod Trail Sled Dog Race appear to be taking an extended break in the ghost town of Cripple, Alaska.
All mushers in the nearly 1,000-mile (1,609-kilometer) race across Alaska must take three mandatory rest periods: a 24-hour layover at any checkpoint, an eight-hour layover somewhere along the Yukon River and another eight-hour layover at White Mountain, which is 77 miles (124 kilometers) from the finish line.
