A group of surfers in Southern California have broken the world record for the most people riding a wave on a surfboard at the same time on June 20.

Sixty-six people, including surf champions and local heroes, rode a 42ft surfboard for 12 seconds to break the record at Huntington Beach south of Los Angeles.

Around 5,000 people watched from the coast, the Orange County Register reported.

Guinness World Record adjudicator Michael Empric said a separate record for whether the 1,300-pound board is the world’s largest will take a few days to determine.

The record was previously held by a group of 47 surfers in the Australian state of Queensland.
