Thousands follow Run Geordie Run's Oz challenge on Twitter

Half marathon done and rewarding myself by reading tweets as I run. #rgrdownunder


The surface is all tiny stones. Really tough afternoon this one. Need to invent a new game for the last 11 miles. #rgrdownunder


Just got off the Great East Highway in time before it got dark. Now on a minor road surrounded by thick bush land. #rgrdownunder


Run Geordie Run!

A North East fundraiser is jetting off today ahead of his latest challenge. Mark Allison, also known as Run Geordie Run, is planning to run across Australia. It's two years after a similar challenge he did in the USA.
