Details of the winter Walk 2026
A great event to walk off the Christmas celebrations, and to kick start your New Year fitness regime! There are Full Marathon, Half Marathon & 10K options, both starting & finishing at The Oval Cricket Ground on Saturday 24 & Sunday 25 January, and take in highlights of the Thames, its historic bridges, and many of the Capital’s key landmarks. Families are welcome, there’s a free winter bobble hat & neck buff, rest stops with snacks, with a special medal and hot food at the finish. Get the ‘Ultra Challenge’ support & hospitality all the way – helping you to push yourself further and achieve something really special!
Whether it’s to enjoy an active day out with friends or colleagues, or to maintain a New Year fitness regime – there’s a London Winter Walk for you! Join as an Individual or as a team, and raise funds for Young Lives vs Cancer along the way.

And here are some of the benefits of joining Team Young Lives vs Cancer:
Every day 12 children and young people are diagnosed with cancer. Yet not one of them has the same experience. All young cancer patients have different needs, opportunities and backgrounds and for some, the systems in place and gaps in support mean that their experiences are much more challenging than others. Far too many children and young people with cancer are experiencing inequality as soon as they are diagnosed due to a ‘one size fits all’ approach throughout much of the system. That’s why the support they receive must look beyond their diagnosis. It should provide them with what they need, so that they can go on to thrive no matter what. That’s why we exist.
We don’t receive any government funding so everything we do is thanks to amazing people like you. From funding our brilliant Young Lives vs Cancer Social Workers to our vital financial grants, your support means that we can be there for children and young people facing cancer, and their families, to ensure that having a cancer diagnosis doesn’t mean you lose what makes you, you.
