Chaos ensued on the N7 last month when a gang of sulky racers took over the road during rush hour

The pastime of sulky racing was taken to a new level last month when a group of four harnessed horses were raced up the inbound section of the N7 during rush hour traffic.

Four men were video taped racing down the N7 near the Citywest during a peak time for traffic, causing a massive backlog of cars to be held up behind the racers.

The Irish Daily Star carry the story on their front page this morning, and pictures show a group of men well armed with video cameras to capture every angle of the race.

A large convoy of cars followed the horses from behind, taking up all three lanes to ensure that traffic was unable to pass.

The races are obviously illegal, and animal rights activists have been up in arms over the last number of days following the emergence of the footage.

Last year a horse died after it was injured when a car attempted to overtake it during a sulky race in Kilkenny, while there are also various video clips on YouTube of races in Cork, Limerick and more on the N7 also.
