massive murray marathon fundraiser to raise awarness of NETs cancers

My younger brother age 37 has always been a healthy bloke however on going to hospital for pain in his kidneys he underwent a lot of tests and scans to diagnose the source of the pain. The Dr's & specialist could not find the cause and were about to diagnose the cause as a fatty liver. Luckily, (or not so luckily) another specialist happened to be inquisitive and had a look at his results and immediately became suspicious that there was a more serious underlying issue causing his symptom’s and ordered a biopsy along with another more targeted PET scan. As suspected these new tests showed that my brother had what is commonly referred to as a Neuroendocrine tumours (NETs). Rob is now being treated but his diagnosis is not great.
Neuroendocrine tumours (NETs) is the umbrella term for a group of unusual, often slow-growing cancers. These tumours develop from secretory cells found throughout the body and which are particularly concentrated in the gastrointestinal system, lung, pancreas, ovary and testes.
I am doing this fundraiser to raise funds to support patients undergoing treatment for NETs and to hopefully one day find a cure or prevention for this cancer. And to raise public awareness about these rare forms of cancers.
The Massive Murray Marathon is a 404 km race over 5 days. My target is to finish in the top 3 for my category. I have previously Kayaked the length of the Murray river 2,500 km's in 45 days and believe I am up for the 5-day challenge of the massive Murray Marathon

Please support me in this worthwhile cause
