Recommended by the people who matter most: trail runners

Amazing community to be a part of in Adelaide. Welcoming, inclusive and very well organized events and social runs.

TRSA has been the most supportive group of people to run with. It doesn’t matter your age or fitness level; everyone is welcome. I genuinely look forward to my social Tuesday night runs, it’s so good for the soul (and heart).

TRSA is a wonderful community organisation and I think the social runs are the heart of it. So many people come into trail running through that route and remain as members.
