"The experience of London is amazing, the amount of crowd support and the number of people watching and cheering on really does motivate you to keep going when it's getting tough.”

"I think working with young people with cancer makes you appreciate your life,” says Teenage Cancer Trust nurse, Claire Swift. “You're in a privileged position to spend time with young people and their families who are going through what they're going through. It does make you realise how lucky most of us are to get where we are without having those upheavals that young people with cancer have.

Teenage Cancer Trust's approach is centred on the needs of young people. It's important to recognise that young people are young people and that's the most important thing about them – the fact that they've got cancer comes second. They're not children and they're not quite adults so it's about having age appropriate care and environments. It's about providing sort of home from home for them when they have to be away from their friends and family.

It’s really sad that not every young person has access to a Teenage Cancer Trust unit, a specialist nurse or a Youth Support Coordinator. Any extra funding that we get will help us to reach young people in areas where we know there's no services provided at the moment."

Claire describes everything about her role as “wonderful”, from supporting the young people and their families through the first days after diagnosis to the pizza nights and excursions. But that doesn’t mean there aren’t tough days. Which is where running comes in! “It's easy to do, you can just put your shoes on and be out the house within 10 minutes. You don't need any special equipment apart from running shoes and a good sports bra! After a difficult day at work it's really good to switch off and go for a run with my music."

She's run the London Marathon an amazing 4 times now: “You've probably watched the London Marathon on television for years and thought, ‘oh I'm going to do that one day’. When you actually do it it's a massive achievement.

Training for a marathon is difficult because marathons are generally run around March/April time so you have to do the majority of your training in the winter and it's tough getting out of bed and going for a run. My top tip is get out there because even when you don't feel like going, after 10 minutes of running, you'll normally forget that you didn't want to go. If I can run a marathon anybody can. On the day the atmosphere will get you round. The last 6 miles are tough but when you've got to that point you know that you're going to finish so just imagine yourself crossing the finish line - it's a wonderful feeling.”
