Portsmouth man runs 100 miles for children with cancer to show your past doesn’t define future
He competes in a marathon in December
A Portsmouth man is turning his personal challenges into a powerful fundraising mission, running 100 miles during October to support children and young people affected by cancer.
Stephen Southern, who grew up in the residential care system and manages multiple mental health conditions, is using running as a way to support his wellbeing, build resilience and raise awareness of the challenges faced by young cancer patients and their families.


Having reached the halfway point of his challenge, Stephen has completed 50 miles and raised £150 for Young Lives vs Cancer, a charity that supports children, young people and their families through the devastating impact of a cancer diagnosis.
Stephen said his challenge is about more than reaching a mileage target. It is also an opportunity to show others that their circumstances and experiences do not have to determine their future.
“Growing up in the residential care system taught me how to fight, and managing my mental health keeps me fighting every day,” he said.
“These miles are proving that our past doesn’t define our future.”
For Stephen, running has become an important part of managing his mental health, providing a positive outlet while helping him work towards personal goals.
His October challenge is also serving as official training for his first-ever full marathon, the Portsmouth Coastal Marathon, which is due to take place on December 20.
Despite the physical demands of running long distances, Stephen remains focused on the bigger picture: supporting young people facing circumstances far more difficult than his own.
“These miles are proving that our past doesn’t define our future - they are fuelling my training for my first-ever full marathon this December,” he said.
“No matter how tough the blisters get, it’s nothing compared to what young people facing cancer go through,” he said.
Stephen hopes his efforts will encourage more people to learn about Young Lives vs Cancer, recognise the vital work it carries out and contribute towards its fundraising efforts.
He said he wanted to raise awareness and show his appreciation for an organisation that helps people facing some of life's most difficult moments.
Young Lives vs Cancer works with children, young people and their families when a cancer diagnosis turns their lives upside down.


Alongside the fear and uncertainty surrounding treatment, families can face financial pressures, the possibility of being separated during treatment and the emotional strain of navigating an unfamiliar situation.
The charity provides support to help families face these challenges and find practical and emotional assistance when they need it most.
According to the charity, every day 12 more children and young people hear the devastating news that they have cancer.
For Stephen, that is a powerful reminder of why his fundraising challenge matters.
His miles are intended to help shine a light on the charity's work and encourage others to support families who may be struggling to cope with the impact of a diagnosis.
