"Each March, the world's top sled dog teams gather in Alaska for the sport's biggest event: the Iditarod Trail Sled Dog Race. In this incredible race, mushers race their dog teams across more than 900 miles (1,448 kilometers) of rough Alaskan terrain. Readers will join Maggie and Alex, two young relatives of an Iditarod musher, as they get an insider's view of the race. They will learn about the Iditarods history, rules, strategies, and much more."--Publisher's description.
