Green Mile (Evening Halloween Edition)

The Green 26.2 Mile HMP Dorchester is a unique marathon event organized by Sussex Trail Events, taking place at the historic Dorchester Prison in Dorset. After a two-year hiatus, the event returns with both a daytime and a spooky Halloween evening edition. Participants can choose to run during the day or night, or even both, navigating the challenging prison stairs.

The night marathon will feature altered lighting to enhance the eerie atmosphere. This event is notable for being the only marathon in the world held entirely inside a prison. Visit the organization's website for the most recent information.
