👻 The New Jersey race scene Just got SPOOKY!
Trials of Miles is thrilled to bring the Boooo-mfield 5K to the streets of Bloomfield! This Halloween-themed 5K is part race, part block party, complete with costumes, fall vibes, and just the right amount of fright. Fly like a bat at the front, cruise in costume with friends, or push your little pumpkin in a stroller—no matter how you join, this is one Halloween morning you won’t want to ghost on. 🎃
Best of all, every ghoul, goblin, and werewolf who signs up helps support the Bloomfield High School XC/Track teams and the Friends of Watsessing Park Conservancy, funding everything from student-athlete travel to new trees in the park. Run fast, run spooky, and join us for a fang-tastic morning of costumes, community, and Halloween fun! 🕸️
