A heavily used bridleway (I suspect motocross bikes) with a series of dips & rises, some of which fill with muddy puddles. The previous dozen or so riders had all wimped out and rode around the side - this guy spotted the camera as he approached me, decided to ham it up, and rode headlong into the puddle for the full mudsplash effect. Result.
