Early estimates showed good attendance at the Runnin O' the Green Saturday in Jamestown, said Larry Knoblich, organizer of the event.
"Better turnout than we thought it would be," he said. "Lot of people at some of the locations."
The annual fundraising event for Elk's Camp Grassick and other causes was canceled last year and postponed a month from its normal March date this year due to the coronavirus pandemic.
The 2019 event, the last held, drew about 1,500 people.
This year's crowd was estimated at about 1,000 people by law enforcement, according to Scott Edinger, Jamestown chief of police.
As of 6 p.m. officers had made one arrest for an open container of alcohol outside a licensed bar, one stolen car and three driving under suspension.
Edinger said one person was also arrested for "threatening the crowd" at one of the parks in Jamestown. It was unclear what charges that individual might face.
Final counts on participants and law enforcement activity will not be available until Sunday.
