This month, Tom Dunn will be set out on a 4,825km self-supported triathlon across the length of Australia's mainland, from Cape York to Wilsons Promontory, raising awareness and money for the Melbourne Indigenous Transition School (MITS).
The triathlon will be comprised of a cycle leg longer than the average Tour De France, a run further than 22 marathons, and a swim greater than 4 crossings of the British channel, equal in total to over 90 Olympic standard triathlons! And he's doing all this completely unsupported, sleeping on the side of the road, and relying only on the generosity of community members.
In previous 'adventures', Tom has raised over $97,000 for charity. If you own a business that can help him out, or if you'd like to find out more information (including how to donate), head to Tom's website here.
