The Great Cycle Challenge is one of Australia's biggest community cycling events, a nationwide challenge that runs throughout October to fight kids' cancer. Riders of every age and ability set a personal kilometre goal, then ride anywhere they like across the month to reach it while raising funds for life-saving research.

Every kilometre supports the Children's Medical Research Institute and its work to develop safer, more effective treatments and find cures for childhood cancer. It is free to join, open to all fitness levels, and built on a simple idea: set yourself a challenge on the bike and help give young patients a healthier future.
