When word gets around that Paulsen plans to compete in the Iditarod, the local community rallies behind him by donating money, food, and essential gear.

When they start to run out of money this neighbor dips into his own savings account to help fund the remainder of the trip and keep Paulsen's dream alive.

As he prepares himself for the 1,180-mile race, Paulsen constantly asks questions and seeks to learn from the officials and the other, more experienced Mushers.

On this detour, Paulsen encounters a moose which, despite being repeatedly shot by a Musher traveling behind him, kills the lead dog of that team.

During the 17 and a half days it takes Paulsen to complete the race he experiences sleep deprivation and hallucinations, freezing temperatures and bitingly cold winds, stunning views, and tragic disasters.

At the end of the story, Paulsen is diagnosed with coronary heart disease and is told that he will not be able to live a normal life.
