"It's probably the craziest thing I've ever done but the most rewarding," Rebecca Miller said as she reflected on the last week.
"This moment I have imagined for two years."
Instead of the 5am starts over the previous eight days, on Sunday morning at a glorious time of 11am Rebecca - with her immediate family right behind her - blissfully jogged her last five kilometres into Westmead Children's Hospital.
The hospital was her final stop after a 355km journey that began at Northparkes Oval in Parkes a week earlier on April 10.
A mission she had been planning for the last two years - but couldn't get started because of multiple obstacles such as injuries and Covid-19 - now an accomplished reality.
Passing through Orange, Bathurst, Lithgow and Katoomba - though not roadside like she had wished because of flood-damaged roads - Rebecca's run, named The Ripple of Kindness Project, has so far raised $57,260 for four charities.
Her goal is $100,000, which will be split evenly between the Leukaemia Foundation, Bandaged Bear, Carrie's Beanies for Brain Cancer and Can Assist.
"It's just a surreal moment to think here I am, that the task of 355km is done. I can't believe it," Rebecca said on Sunday.
"What a week, I can't even put it into words."
Rebecca passed half way of her fundraising goal ($51,530) by the time she arrived in Parramatta on Saturday, day eight, completing a 46km leg to get her to 350km.
Of course an incredible commitment such as this doesn't come without its challenges, like a hip injury during training that had her sidelined for six months, delaying the start of her run.
Day three and five were her hardest days where there were moments she said she didn't think she'd get through it.
"But I did," she said.
"My husband who stuck by me on those hard days, said to me 'just remember why you're here'.
"Let me tell you it's just amazing what the human body and mind can do."
Her knee began to play up along the way, so bad at one point Rebecca was forced to use a cricket pitch in Katoomba for the even ground.
"There were times my legs were so sore I can't even put into words the pain," Rebecca said.
"There were times where my husband had to carry me to the car when I finished because I could not walk another step.
"And it's funny, the last couple of days it's been easy, it's like your body gets used to it. It's such a weird feeling.
"There's been so many things that have happened this [last] week, what it has shown me is that I am stronger than I ever thought I could be and as human beings we are capable of so much."
Rebecca has been overwhelmed by all the messages she's received, all the words of kindness and all the donations.
She said donations have been coming in from all over the world.
"All the amazing things I've been through this whole experience... it's just been utterly mind-blowing," she said.
Amazing things like strangers offering her and her support team accommodation along the way, and mothers calling to tell her their children want to donate their $10 allowance to The Ripple of Kindness Project.
"My son Toby went to football training [last] Thursday night and on Friday when they (her children) came to meet me, he handed me some money, $80, that his football team, all the boys had thrown in $10 or $5 each to be able to contribute to The Ripple of Kindess Project," Rebecca said.
"There's so many stories like that.
"Thank you so much to everybody, it's been the most heartwarming feeling."
Head of Individual and Community Supporters at the Leukaemia Foundation, Rachael Lance, said they are extremely grateful for the support of Rebecca through her Ripple of Kindness Project.
"We're thrilled that she chose us as one of the beneficiaries of her run and on behalf of the Leukaemia Foundation and blood cancer patients across Australia, we extend our heartfelt thanks," she said.
"Money raised through big-hearted fundraisers and donors such as Rebecca, ensure that every single Australian who hear the words 'you have blood cancer,' regardless of where they live, can access the support of the Leukaemia Foundation free of charge.
"It also assists us to advocate for equitable access to new therapies and treatments, and to further invest in vital research.
"Four in 10 Australians diagnosed with blood cancer, like Lilly [Wyburn from Parkes], live in remote and regional areas.
"In 2020 the Leukaemia Foundation supported around 540 rural and regional families with a place to call home at no cost while receiving treatment in the city.
"Sadly, we're bracing for these numbers to increase this year and in years to come as the prevalence of blood cancer continues to rise."
The Ripple of Kindness Project officially began two years ago when Rebecca shaved her head with her best friend Marguerite Burns who had been diagnosed with breast cancer. It was further enhanced after the passing of Lilly who battled leukaemia for most of her young life.
Rebecca really wanted to contribute to raising awareness of childhood cancer, particularly blood cancer like leukaemia and brain cancer.
"They're still the two biggest killers in children," she said.
Rebecca also wanted to support the parents of the these children.
"It's very tough for country families and there are so many expenses involved. Families have to move their whole lives to the city [to access ongoing medical treatment]," she said.
"To sit here today knowing that I'm running into the hospital, it's not just me - I may be the face here - but every single person who's followed this journey has helped me achieve this outstanding amount of money that we're going to be able to help so many people," she said on Sunday.
Rebecca is still accepting donations on her Go Fund Me page for anyone wanting to donate.
