Iron Will (1994)

His father's demise leaves young Will Stoneman (Mackenzie Astin) and his mother struggling to save their farm from financial ruin. When options run out, Will registers for a marathon dogsled race, which touts a prize of $10,000, but is barred by race benefactor J.W. Harper (David Ogden Stiers), who believes Will is too young. However, a reporter (Kevin Spacey) with dubious motivations advocates on Will's behalf. Soon enough, Will is back in the race, hoping to save his father's legacy.
