Participants will ride 1980s and ‘90s Urals which were pretty much the same as in 1940 when the Russian army took the German BMW R71, pulled it apart, copied it and slapped a Ural badge on.
Teams are provided with a mapping file for their GPS, the necessary spares and tools to fix and maintain their bike, and snow chains and ice spears for pushing relentlessly forwards once they hit the crevasse fields and cracks on the ice.
A ground crew and 4×4 emergency support vehicle will track teams in case of genuine emergency.
Entry fee is £3795 (about $A6165) per team.
Raising funds for environmental charity
All riders are also asked to raise at least £1000 (about $1600) for the official charity, Cool Earth, an environmental charity that works with indigenous communities to halt rainforest destruction.
The Ice Run has raised more than $100,000 since it started in 2012.
