What is Project Impossible?


William Corlett is a young man hailing from the Blue Mountains, promoting positive mental health amongst young men. Will strives to support all Australians affected by suicide.

To raise awareness, Will made it his mission to raise $200,000 for Lifeline by running the Tassie 200, from Launceston to Hobart in 24 hours in 2023. With no previous experience or plan and just the support of his best mates. He called the effort Project Impossible.

Fuelled by the experience and support, Will takes on his next Adventure Project Impossible: King of the Mtns on the 23rd of June 2024.

The Tassie 200

On the 22nd of February 2023, William Corlett attempted to run 200km, the length of Tasmania, in 24 hours.

With relentless support from his three red-P-Plate-wielding mates, they embarked on Project Impossible. From Launceston to Hobart, Will ran to raise $200,000 for Lifeline Australia.


Plus they filmed the whole thing. Project Impossible is now a short film touring as part of the 2024 RunNation Film Festival.
