May Day was Lei Day in Hawaii.

Volunteers hoping to set a record for the world’s longest lei strung together flowers that stretched for more than a mile at Kapiolani Park in Waikiki on Thursday, organizers said.

Video, photos and witness statements documenting the lei, which measured 5,336 feet in length, will be sent to Guinness World Records, organizers said.

Success seems all but certain, because organizers say there currently isn’t a Guinness record for the world’s longest lei.

Mayor Mufi Hannemann is expected to announce within a few weeks whether the record is official.
