Stawell Secondary College has thrown their support behind 2008 graduate Greta Duke who will tackle the gruelling Bravehearts 777 Marathon.
Between July 1-7, a maximum of 30 runners, including Ms Duke, will each tackle seven Marathons, over seven states, in seven days.
Bravehearts is the only Australian charity specifically dedicated to preventing the crime of child sexual assault.
Ms Duke said she felt compelled to take part in the event through her occupation as a case worker in adult mental health.
"Though my work I hear a lot about child sexual abuse so I thought this marathon was a way I could advocate around this issue," she said.
"I see running as a good platform to spread the word and get the conversation happening. It's a great way to lead into a more sensitive topic when people ask why I am running.
"I have two working arms and two working legs so running is something I can do to create awareness."
Ms Duke has previously participated in marathons and has been training for more than six months for the event in July.
"I have pretty solidly trained for six months for the event," she said.
"My weeks consist of about 80-100km of running per week.
"I am looking forward to having a rest afterwards, but I'm sure something else will come up in the pipeline."
In addition to this already incredible feat, each runner will commit to raising a minimum of $10,000 for the Bravehearts' Charity.
Ms Duke said she was proud her former high school wanted to jump on board to raise awareness.

"Bravehearts do a lot of work in schools so it's lovely and ties in really well the school has decided to jump on board and get behind me," she said.
"It's such an important issue within society with the statistic of one in five children in Australia impacted by sexual abuse."
College assistant principal Murray Hart said students would wear casual dress on June 13 with a "white" theme to resemble the white balloon symbol of the Braveheart charity.
"Students will make a gold coin donation on the casual clothes day," he said.
"The school community is invited to donate to Greta's fundraising page."
Bravehearts' vision is to make Australia the safest place in the world to raise a child and services include counselling and support services, preventive education, child protection training, research, advocacy, lobbying for legislative reform.
