The challenge invites participants to walk 96km throughout the month of March to honour veterans and their families.
Walkers, who can participate individually or as a team, can also raise money for not-for-profit Soldier On, an organisation that supports the mental health and wellbeing of current and former Australian Defence Force personnel.
“The March On challenge is about more than just kilometres — it’s about supporting our veterans and their families, raising awareness and helping prevent veteran suicide,” Ms Humphreys said.
“It sends a powerful message: they are valued, supported and never forgotten.”
Diagnosed with orthostatic tremor two years ago, Ms Humphreys has battled with rapid, involuntary muscle contractions in her legs when standing.
Having completed a number of walking challenges to raise awareness about the rare condition previously, she said she never wanted to be restricted by OT.
“On a personal level, I don’t want to let a diagnosis define or limit me,” Ms Humphreys said.
“If anything, it’s become a driving force behind my determination — and maybe a bit of stubbornness — to keep going.
“By challenging myself, I hope I can also encourage others to stay positive, focus on what they can do, and not give up.”
By the 19th day of her March On challenge, Ms Humphreys had walked the 96km of the Kokoda Track, saying “it happened almost without me realising”.
With 12 days left to go, she kept going with the aim of completing the return journey.
“When I signed up for the March On challenge, I honestly wasn’t sure I’d make the full 96km, so to not only reach that goal but go well beyond it was something I’m really proud of,” Ms Humphreys said.
“I finished on 164km — just 28km short of completing the full return journey.
“Watching the kilometres add up each day, and sharing the journey with others along the way, was incredible rewarding.
“It really showed me that you don’t always know what you’re capable of until you give it a go.”
Ms Humphreys also raised $667.80 for Soldier On, adding to the record-breaking total of $3,267,502 amassed by participants around Australia.
Although she experienced challenges on the way — walking beneath storm clouds on her first day and pushing herself through not feeling her best — Ms Humphreys said she didn’t want to stop stepping for change any time soon.
“Looking ahead, I’d love to see more awareness and support for orthostatic tremor,” she said.
“One day, I hope to take part in something similar that raises funds for conditions like mine.
“The March On challenge showed me that when people come together, real change is possible — and that’s what gives me hope.
“With September being OT Awareness Month, I’m looking forward to continuing to raise awareness and make a difference, just like I did last year.”
