In recent years the ‘Dirty Boys’ component of the Cairns to Karumba Bike Ride has grown enormously in popularity.

With the increased number of riders wishing to take part, ride organisers (Milboe Ltd) are keen to ensure that the logistics are sufficient to maintain the integrity of this wonderful riding experience, whilst also ensuring the safety of our participants.

To help with this process, the 2022 ride will require all dirt riders to complete an expression of interest. This will ensure that we have a group of riders who have the riding experience to handle the conditions of this multi-day event and a bike that can handle the rough outback terrain.
