The zombies stumbled from Convention Hall on Asbury Park's boardwalk up Cookman Avenue to the downtown area Saturday, NJ.com reported.
The Annual New Jersey Zombie Walk set a Guinness World Record in 2010 for the world's largest gathering of zombies when 4,093 zombies were in attendance.
This year organizers said they believed more than three times that record amount would be in attendance Saturday.
"I never imagined that it would ever get this big and that we would still be doing this," said Jason Meehan, 31, of Neptune, who started the walk with his ex-wife, Christina, in 2008. "But not only is it still here, it's getting bigger every year."
The event was family-friendly and continued into the night with several zombie-themed events, including an after party at the legendary Stone Pony.
"This event is always fun, especially for zombie lovers," said Thomas Norman, 39, who has been in attendance at all five zombie walks. "It keeps growing every year and the costumes keep getting better."
