Losing his sister to melanoma at the age of 30 changed the course of Mr McGowan's life as he and his family struggled to comprehend their loss.

Nearly two year's after 30-year-old Tess McGowan died form melanoma, just 11 months after diagnosis, Mr McGowan is making sure his sister's story is not forgotten.

In ride a he dubbed "Cycling to March", Mr McGowan hopes the 1900 kilometres travelled from Adelaide to Sydney will help increase the awareness of melanoma while also raising funds for the Melanoma Institute of Australia.

In 2011, Mr McGowan was pursuing his passion for cycling, riding across the United States, when he received a devastating call from his father, telling him his beloved sister had been diagnosed with melanoma.

Mr McGowan said prior to his sister's diagnosis he had no idea of the incidence of melanoma in Australia.

"They told me melanoma is the most common cancer in 19 to 34 year old and I thought wow this is pretty serious and this is my age group," he said.

During her treatment, Tess went on a trial drug, which gave her three extra months.

While to many people three months may seem like nothing, Mr McGowan said this time meant everything.

"This time allowed us to say exactly what we wanted to say," he said.

"It also allowed Tess to write letters to her daughter, who was one, telling her what she wanted for her when she was ten and twenty and so on," he said.

In the aftermath of his sister's death Mr McGowan and his family managed to raised $7000 but now they hope to raise much more.

With the ride ending in Sydney later this week, Mr McGowan says there will be a final celebration in Centennial Park, where he spent months training.

"The health minister will be there, Stephanie Rice who is an ambassador for melanoma will be there," he said.

Mr McGowan's real wish, however is to have the Prime Minister in attendance.

"I know if he will publicly recognise melanoma as a problem then people in Australia will listen," he said.

Mr McGowan said he hopes his work in raising awareness around melanoma, will allow Tess' dream of a cure to come true.
