Naked Pumpkin Run

The Naked Pumpkin Run is an annual event in the United States where participants run a course through a town whilst nude save for shoes and a carved pumpkin on their heads. Runs are held in Boulder, Colorado; Seattle, Washington; Portland, Oregon; and Arcata, California.

The event can be traced to 1974 when hundreds of University of Colorado at Boulder students ran across the campus in the nude in a failed attempt to set a Guinness World Record.

Starting in 2001, dozens of people have taken part in a Halloween run through Boulder's streets wearing only shoes and a hollowed-out pumpkin on their heads.

In 2008, 150 people ran naked for the 10th official annual Naked Pumpkin Run. In 2009, local police threatened participants with charges of indecent exposure and registration as a sex offender if they were arrested during the run.

Boulder also hosts an annual clothing-optional bike ride that protests the use of fossil fuels.

Runners in Hamilton, Ontario Canada had their first Naked Pumpkin run on October 30, 2015. Ten runners participated in the inaugural event, without arrest or incident.
