SALT LAKE CITY (AP) — A protest of Utah’s uptight laws that featured people running through the streets of Salt Lake City in their underwear has set a new world record.

Guinness World Records says the Utah Undie Run broke the previous record for largest gathering of people wearing only underpants or knickers by 1,720 people.

Records officials say 2,270 people stripped to their underwear during the Utah Undie Run on Sept. 24. The previous record of 550 people was set last year in Great Britain.

Utah Undie Run organizers are planning another run next August. The event’s goal is to protest the state’s conservative politics.
