The timed portion of the race, which typically lasts nine days or longer, begins on Monday in Fairbanks, about 300 miles (482 km) away. Traditionally held in Willow, the timed start was moved to Fairbanks this year to accommodate an alternate trail selected after race officials deemed sections of the traditional path unsafe.
