Stray dog Arthur bonds with adventure team; completes gruelling extreme-sport challenge

Arthur was a bedraggled, hungry stray when a kindly stranger offered him a meatball. The man was Mikael Lindnord and he was leading a team in one of sport’s toughest challenges.

The team finished their canned meal and set off on a 40km jungle trek - stage three of the Adventure Racing World Championship in Ecuador, a race that combines gruelling challenges in trekking, mountain biking, kayaking, navigation and more.

A few kilometres in, they realised the stray was following them. And he refused to leave.
