Voters will decide Tuesday between Charles Adams and Greg Allen for Forsyth County's next clerk of Superior Court.
The post is being vacated by Doug Sorrells, who is retiring after 12 years of service.
Both Adams and Allen are Republicans. There is no Democratic challenger on the Nov. 4 ballot.
Allen took the lead in the July 15 election with 45 percent of the vote, or 4,908 votes, while Adams came in with 34 percent, or 3,644 votes.
Walter Brown, who sought the post, received the remaining 21 percent, or 2,230 votes.
Adams, a white collar crimes investigator with the Forsyth County Sheriff's Office, said he was disappointed with voter turnout for the primary, but is excited about the runoff.
"My campaign is moving forward and I'm meeting the citizens of Forsyth County and soliciting their votes," he said.
"I'm putting my signs out, I'm talking to people, shaking hands with people, meeting people. I'm contacting a lot of folks online and putting my Web site out."
Allen, a sales executive, said he's both excited and nervous about the upcoming runoff.
"I'm looking forward to having a resolution," he said. "I'm getting my signs out to the polling places, calling people and e-mailing people and reminding them to vote."
