Green Mile Night Marathon

The Green Mile Night Marathon is a unique running event taking place at the former HMP Dorchester, making it the only marathon held entirely within a prison. Scheduled for November 2, 2024, this event features both a day marathon and a spooky night edition, allowing participants to choose between running in daylight or darkness. Head torches are required, and the atmosphere is enhanced with dim lighting to create a thrilling experience.

Entry fees vary for affiliated and non-affiliated runners, and discounts are available for those participating in multiple events within the series. Visit the organization's website for the most recent information.
