Remy Deville, a French competitive shooter, posted these videos from some matches. I assume they were in France.
First up is a stationary bike. The shooter’s pistol is unloaded and sitting in the little box. The box is tied to the back wheel. The shooter must pedal to bring the small box up the ramp so he can retrieve it, load it, and shoot the stage.
Next up is a little roller coaster cart rolling backwards and the shooter shoots the targets as they are made available.
