The Karnu Rally is an annual self-supported bikepacking event that challenges riders to traverse the rugged terrains of South Australia. The 2025 edition is set to commence at 7:00 AM on October 4, 2025, departing from the Torrens Boat Sheds in Adelaide. Participants can choose between two route options: a 730 km course and a more demanding 1,180 km route. Both paths wind through the Flinders Ranges, incorporating segments of the Mawson Trail and passing through notable areas such as Spring Gully Conservation Park, Mount Remarkable National Park, and Ikara-Flinders Ranges National Park. The event emphasizes self-reliance and adventure, offering riders the opportunity to experience the diverse landscapes of South Australia.

A Hardtail MTB is the right tool for Karnu Rally. Set it up with 2.2-2.4" Tubeless rubber and gear it low — a 30-32T (1x) chainring and 10-52T cassette will keep you spinning on the steeper sections.
Karnu Rally carries an overall difficulty rating of Intermediate. The terrain itself is seriously technical, unforgiving terrain throughout, and conditions tend to run mild and generally comfortable.
