Running a marathon is a physically and emotionally draining experience that takes many hours to complete and many more to train for.
Completing the London Marathon on April 22 will be a great achievement for 23-year-old exercise physiologist Matt Conti.
He will run the 42km race less than a year after being told that he was in remission from Hodgkin's lymphoma, which he was diagnosed with in 2010.
Mr Conti said that his health and fitness before his diagnosis had helped get him through the chemotherapy and radiation treatment.
Eager to give back to the people that have helped him through his illness, Mr Conti is running as an ambassador to raise money for the Leukaemia Foundation. He has already raised $18,000 of the $25,000 target he has set himself.
"I get the newsletter from the Leukaemia Foundation and there was just a small article on the back of it that said 'could you run a marathon?' and mum sort of pointed it out to me as a joke and I gave it a little bit of thought and I thought why not," Mr Conti said. "I really have so many family friends all around me who have really blown me away with how generous they've all been and how willing they are to help."
His doctor is helping make sure he does not overdo the training.
