Boooo-mfield 5k is a running race on October 24, 2026 in Bloomfield, NJ, with entry fees from $20 to $38.
From the Organizer
The Boooo-mfield 5K is more than just a run — it’s a Halloween-flavored block party right in the heart of the Watsessing community, starting and finishing outside Skiddoo and Narda’s Café. Whether you're racing in costume, walking with friends, or pushing a stroller to the finish, this is a fall morning you won’t want to miss.
All proceeds from the event support local community efforts — including the incredible work of the Friends of Watsessing Park Conservancy, a volunteer-driven group dedicated to preserving and enhancing one of Bloomfield’s most beloved parks, and the Bloomfield High School Cross Country and Track & Field teams, helping fund gear, travel, and meet expenses for student-athletes.
Come for the run, stay for the music, costumes, food, giveaways, and spooky-fun vibes!
