My Name is Keira Norton, and in April 2026, I’ll be running the London Marathon. 26.2 miles. With thousands of others. But my race is a little different.

Because I’ll be running with cystic fibrosis — a genetic, lifelong, and currently incurable condition that affects how my body works, especially my lungs and digestive system. It’s something I carry with me every minute of every day, and it’s shaped so much of who I am.

You might not see it when you look at me. That’s the thing with CF — it’s invisible on the outside. But on the inside, it can feel like I’m constantly breathing through a straw, even on the better days. On the harder days, it feels like my lungs are filled with concrete. I cough until my ribs ache. I clear mucus from my lungs, over and over, just to be able to catch a breath. And I take dozens of tablets every single day just to help my body absorb the food I eat — just to keep my body going.

Daily life isn’t simple. Every morning starts with treatments. Nebulisers. Inhalers. Chest physiotherapy. And that’s before breakfast. Every illness hits harder. Every cold risks turning into a chest infection that could mean weeks of IV antibiotics. So every thing I do; it's to keep myself in good health.

But, I’m not doing this alone. I’m raising money for the Cystic Fibrosis Trust, an organisation that has walked—and run—alongside people like me for years. Their research, support services, and relentless fight for change have already helped extend lives and improve quality of life for thousands. But there’s still so much work to do.

The harsh truth is: cystic fibrosis is still a life-limiting condition. But with your help—your support, your donations, your belief—we can help rewrite that story.

Your donation won’t just be helping me reach a fundraising target. It will be helping fund cutting-edge research. It will be supporting families in crisis. It will be giving children born with CF a better, brighter future.

So whether you can give a little or a lot, I ask you—please support this cause. Help me make every mile count. Help me prove that no diagnosis, no struggle, no statistic can hold us back when we run together.

Thank you for standing with me.
