Overview

Conquer the mighty UC Stromlo Forest Park and immerse yourself in the thrill of this legendary "monster circuit." Spanning almost 30 kilometres, this iconic race course is packed with Stromlo's signature singletrack, technical climbs, and rewarding descents—and in 2026, the stakes are higher than ever.

For the first time, the event hosts the 2026 Australian MTB Marathon National Championships. This is your unique chance to rub shoulders with the nation's fastest pros and most dedicated elites. Whether you're lining up for a "cheeky" single lap or the classic two-lap challenge, you'll be racing on the same world-class stage as the athletes battling for the prestigious Green and Gold jerseys.

Since 2010, riders of all levels have made the Shimano 100 a staple of their racing calendar. They've kept the inclusive Rocky Trail "vibe" riders love, but dialed up the atmosphere. Experience the electric energy of a National Championship event village, cheer on the elites in the three-lap title race, and then push your own limits.

Make it a weekend in the Capital this Spring. Pre-registrations at the Event Hub and Practice on Saturday from midday and Race Day on Sunday from 9am. Whether you're a local hero or traveling from afar, the 2026 Shimano 100 is your invitation to be part of Australian cycling history. Pick your distance and race alongside the best.
