This clip posted on Vimeo is titled "Bryan and Kaia." Bryan is the mountain biker, Kaia is his border collie. And as much as Bryan loves to ride, Kaia loves to run - she blazes down the biking trail through forest near Vancouver, B.C., racing ahead of Bryan and his bike.
The video was shot by Jonathan Kang of Foxwood Films. (Via Laughing Squid)
