SYDNEY TRAIL MARATHON

RUNNERS GUIDE

WELCOME TO THE SYDNEY TRAIL MARATHON

Thank you to every single one of you who has registered for the Sydney Trail Marathon in 2025. It’s been eighteen months since the last STM and we can’t wait to see you all back in Bidjigal Reserve

Bidjigal reserve holds significant value to many. I’ve run countless hours beneath the towering eucalypt canopies and we’re very lucky to still have this slice of bushland relatively untouched in the middle of Sydney. 

As the race day approaches, we promise to do everything we can to ensure you all have a great day running through the bush. If you have any questions, please don’t hesitate to reach out

Alex Treglown, Event Director
