The legend lives on. Australia's greatest and longest running gravel monument. This will be the 10th anniversary edition and we want you to join us.

Starting with registration on Friday night at The Roundabout Inn, we'll then get an early night and gather at 5am for the Anzac Day dawn service in Gloucester. The Monument riders will then set off first, followed by the Colt and Remington a little later in the morning.

Saturday night we'll all gather at the Avon Valley Inn and welcome the Monument and Flashpacker riders as they arrive to join the most memorable gravel celebration ever!

Sunday morning will be an optional informal coffee ride.

Choose from a number of course options:

The Monument: 256km and 4,785 vertical metres
The Colt: 93km and 1,460 vertical metres
The Remington: 42km and 523 vertical metres
The FlashPacker: Choose from a number of fully vetted routes starting in different locations and ride self-supported to arrive in Gloucester the evening of April 25 and join the celebration. This is designed as a multi-day bike-packing experience.

History: The Barrington Tops lies at the boundary of three Aboriginal territories, the lands of the Worimi people of the south-east, the Biripi people of the east and the Wonnarua people of the west.
