The Rainbow Runners is a true story of a sled dog adventure told by Alaskan Husky, Nija JaJa, the youngest member of the team, who along with her uncle-buncles and brother set out to follow a dream to participate in a long-distance race through the Swedish mountains. With fewer dogs in the team than is common for such a race, the team begins their journey with an uphill battle. During preparations they experience what it means to build team, and not just a functioning team, but a team that is flexible and adaptable to changing conditions; a team that is built on recognizing and celebrating the unique strengths in each team member; and a team that keeps sight on their own dream, even when others doubt their ability.
The story culminates in the 250 kilometers long distance race during which they get caught in a white-out on a mountain top. For more than five hours they struggle to keep themselves safe in the storm and eventually navigate their way off the mountain top down to the final checkpoint. With 89 kilometers left in the race and only a few hours before the race officially closes, the team leaves the last checkpoint at 4 a. m. and does what it takes to cross the finish line demonstrating the power of persistence, the importance of listening to your heart, working together, and believing in yourself.
