Campaign by OnePlusOne Marriage and Partnership Research
At OnePlusOne, we want to help build better futures for these children and their families. Join us by donating as we run the 2026 London Landmarks Half Marathon to raise funds for supportive family resources.
Support the campaign →The London Landmarks Half Marathon is scheduled for April 12, 2026, featuring a scenic route through iconic landmarks in Central London.
Date: The marathon will take place on 12 April 2026.
Route: This half marathon is a closed-road event that starts on Pall Mall and finishes by Downing Street. Runners will pass many of London's most famous landmarks, including Big Ben, St Paul’s Cathedral, Nelson’s Column, the Tower of London, and the London Eye.
‘Our research does not fill books which lie on shelves gathering dust. Every bit becomes the basis for the development of active preventative work.’
Jack Dominian — Founder, OnePlusOne
Just as a race is run, children in separated families must face their futures one step at a time. We run to help make sure they don't feel alone in their race.
When a child has an unstable family support system, their futures are put at risk.
According to recent research, these children are “more likely to be disadvantaged across a range of outcomes including emotional wellbeing and education.”
However, this study also says that the impact of separation on a child is directly linked to the way their parents interact with each other, and how they get along as co-parents.
You can help support positive family relationships by donating as some of our team run the London Landmarks Half Marathon to raise funds for supportive family resources.
Your donation will go towards building evidence-based resources that encourage greater stability for children and their parents, even after separation. We have already had great success with our app, Separating better, which allows co-parents to set boundaries and terms in a neutral digital space.
Our valuable work will continue to help people across the UK 'get on better' - something we can all learn from!
