The Sydney Trail Marathon is a trail running event held in Sydney that uses courses through bushland, sandstone escarpments, and sweeping valleys relatively close to the central business district. The event offers multiple race options under the names STM 42 and STM 21 and is scheduled over the long weekend on Sunday October 4th and Monday October 5th.

Event services and inclusions listed by the organiser include a premium event shirt, a finishers medal, aid stations on course, and free race photos provided to entrants.
