A-line is one of the most famous trails in the world, so why not have a mountain bike race down it? That's what the Air DH is and some of the best riders in the world came to put a time down, or you came to get involved in a huge whip train!
For such a fast race there seemed to be very little footage of the riders actually going fast. So much slo-mo of scrubs and whips, which, while making for a sick edit, don't really show how fast or wild the riders really are going.
