One member of the main bunch, Baden Cooke, has other worries - the 2003 green jersey winner has a puncture in his rear tyre.
1210: Frenchman Nicolas Portal looked to have made a surge in pursuit of the four escapees, but it was soon clear he had simply rode ahead of the peloton to make a stop and say hello to his family.

1200: The leading group are now two minutes and 40 seconds ahead of the peloton, as the pace is once again impressive despite a road-level temperature of 43 degrees Celsius.
