The Chain Reaction Challenge is a seven day 1000km bike ride from Canberra to Melbourne, held between March 8 and March 14.
The riders taking part in the gruelling challenge are executives from a range of Australian Businesses.
Money raised through the event will be used to help critically ill newborns through The Starlight Children’s Foundation and the Monash Neonatal Intensive Care Unit.
Already for 2008 the Chain Reaction Bike Challenge has raised over $480000.
