About the Event

On Halloween night, the city transforms for the annual Haunted Half Marathon. Runners will navigate through eerie neighborhoods and historic districts under the glow of jack-o'-lanterns and glowing pumpkins. The course winds past haunted houses, local cemeteries, and spooky landmarks that are typically off-limits to visitors. As participants make their way along the route, they'll encounter costumed characters at various checkpoints who will cheer them on with festive treats and spirited encouragement. The event culminates in a thrilling finish line celebration complete with trick-or-treat stations for runners of all ages. With its unique blend of frightful fun and community spirit, this half marathon is an unforgettable experience that captures the essence of Halloween.
