Hubble Bubble & Ghostly Mile 2026

Hubble Bubble & Ghostly Mile is a Halloween running event held on the Leeds to Liverpool Canal at Kirkstall. Race options range from a 1-mile fun run to a 50km ultra. The longer distances include 10K, 10 miles, half marathon, 20 miles, marathon, and ultra, with the Ghostly 1 Mile Fun Run offering a shorter option for children and families. The course follows a flat, out-and-back path along the canal towpath, providing straightforward navigation and consistent footing instead of a technical trail. The 20-miler consists of two 10-mile laps, and the marathon comprises two half-marathon laps. Costumes are encouraged, with prizes for the best Halloween outfits. All finishers will receive custom medals and Halloween treats. The races are Trail Running Association licensed, and marshals and aid stations will be present to support participants.
