Sydney Trail Marathon

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. The organiser also publishes race logistics, training tips, FAQs, and recap material to help runners prepare and review their race. A runners dashboard is available for competitor management.

The presentation emphasises course scenery in bush and rugged sandstone country and describes the event as a world class production. Social media and organiser contacts are listed for further information. Visit the organization's website for the most recent information.
