Hundreds of skateboarders defied a court ruling on Saturday, gathering on the Upper West Side of Manhattan and then riding down Broadway to the Financial District, in an annual longboard race that a State Supreme Court judge had declared unlawful two days earlier.

The unexpected judicial intervention in the race, called the Broadway Bomb, caused some participants to worry about being arrested and others to say that they were more determined to take part.

In the end, the race proceeded with little incident. As skaters arrived at the finish line, near the sculpture of a charging bull at Bowling Green, some even posed for photographs with police commanders.

No arrests were reported.

Still, there was some tension on Saturday morning as police officers equipped with scooters and a sound cannon flooded the area near the race’s starting point at Broadway and 116th Street. Some skaters decided not to participate. Others gathered several blocks from Broadway, hoping to avoid the police.
