On October 25, 2025, the Hubble Bubble Day 1 & Ghostly 1 Mile invites runners of all levels to embrace a spooky spirit while challenging themselves on an entirely flat out-and-back course beside the Leeds‑Liverpool Canal in Kirkstall. Distances range from a leisurely 5K to a full ultra‑marathon, culminating in a family-friendly Ghostly 1 Mile starting at 4:30 PM. Participants are rewarded with Halloween treats, bespoke medals, spot prizes, and a festive atmosphere—costumes are encouraged but not required. With aid stations every three miles and a traffic‑free trail, it's both beginner-friendly and ideal for seasoned runners chasing fast times. Organized by It's Grim Up North Running, this event brings community, costumes, and camaraderie to Bramleys and beyond.
