Dean Hall, the only person to have swum the entire length 184 miles of the Willamette River in Oregon, USA, is at it again. When Hall completed his historic swim in 2014, he was battling two forms of cancer, leukemia and lymphoma.  Merely weeks after setting the Willamette river record doctors were stunned when they found the leukemia was gone.  Hall plans to swim the River Shannon as a way to continue to prove to the cancer patients around the world that you don’t have to give up your dreams or your drive simply because you have received a diagnosis.  He will also be raising money for the Childhood Cancer Foundation of Ireland during this 20-stage swim which starts on June 5th.
