Full title reads: "Yorkshire. Motor cycling's 'Grand National'. 62 out of 94 finish in famous Scott Trails - a tribute to riders and machines - the 23 mile course of 'frightfulness' had to be negotiated twice."
Various shots of men riding motorcycles over rough terrain. Some of the motorbike's get stuck in deep mud and have to be helped out. People stand and judge as the bikes ride through stream. Some of the water nearly submerges the bikes. More shots of motorbikes negotiating the course.
Shots of male and female competitors shaking hands.
