Arthur the King

Over the course of ten days and 435 miles, an unbreakable bond is forged between pro adventure racer Michael Light and a scrappy street dog companion dubbed Arthur. As the team is pushed to their outer limits of endurance in the race, Arthur redefines what victory, loyalty and friendship truly mean.

In 2015, in Costa Rica, Michael Light, an American runner, and his adventure racing team gets stuck on the first day after their leader takes the poor decision to kayak against the tide. Leo, one of the members of the team, is outraged that Michael has not paid attention to their opinions.
