The pinnacle of Australian marathon mountain biking arrives at UC Stromlo Forest Park. The 2026 National Marathon Championships represent the definitive meeting point for the country’s elite talent, industry leaders, and most dedicated competitors.

Contested over a rigorous three-lap format on the famed 30 kilometre Shimano 100 “monster circuit,” this event is designed to crown the best of the best. For Elites, Pros, and high-performance Juniors, this is the official quest for the National Title and endorsed by AusCycling. Expect a course that rewards technical prowess, tactical intelligence, and raw endurance. Pre-registration and Practice on Saturday from midday and Race Day is on Sunday from 9am.

Beyond the hunt for the jersey, the event serves as a high-value hub for the cycling industry and sponsors. Set against the backdrop of a Canberra Spring, the Championship weekend offers unparalleled brand visibility and a chance to engage with a highly concentrated demographic of passionate cyclists.

While the three-lap marathon is the championship race, the event maintains its connection to the broader community with one-lap and two-lap classifications. Expect a big turnout and a high-stakes, “big race” atmosphere that resonates from the start line to the podium.

Come and witness the intensity of National Championship racing in Canberra and continue the Shimano 100 legacy!
