Thousands of teenage girls in Finland are competing in national show-jumping competitions using toy horse s.

The trend known as ‘hobbyhorsing’, has trotted out of lounge rooms and into sporting arenas around the nation.

Participants compete against one another in show-jumping, dressage and other equestrian events.

The Times reported the sport is estimated to involve over 10,000 participants.

Hobbyhorsing may seem like a bit of a joke but the girls undergo very real training sessions in order to refine their skills.

Oscar nominated director Selma Vilhunen directed the documentaryHobbyhorse Revolution,that captures the fast-growing phenomena.

Girls in the documentary explain how the hobby has improved their fitness, craft-making skills and social life.

I'll bet this isn't the last we'll hear of such a stud idea.
