Ron Clarke's Heart Stops at the Mexico Olympics

At the 1968 Mexico Olympics, the world looked on in horror as the Australian runner, Ron Clarke the race favourite, collapsed at the finishing line of the 10,000 metres. His heart had stopped.

The Australian team doctor, Brian Corrigan, ran to him and managed to get his heart started again.

Clarke had run out of oxygen because of the high altitude in Mexico City.
