If you know me, you'll know I'm not exactly built for running. Yet somehow, here I am, preparing to take on the Royal Parks Half Marathon for the sixth year in a row.

Every year I ask for your support because of a cause that means the world to me, and a young man who inspires me every single day: my nephew, Oscar.

Oscar is now 16 and lives with Duchenne Muscular Dystrophy (DMD), a rare and progressive muscle-wasting condition that primarily affects boys. Duchenne gradually takes away the ability to walk, move independently and, ultimately, even breathe without assistance. Despite this, Oscar faces every challenge with a positivity, courage and determination that never fails to amaze me.

He's a huge Arsenal fan, a Star Wars expert, and the proud owner of what must be one of the finest Star Wars Lego collections in the country. Most importantly, he's an incredible young man who refuses to let Duchenne define him. He plays Powerchair Football (in the Premier League, no less!) with passion and skill, and I wouldn't be surprised if one day he pulls on an England shirt (before you ask, Wales don't have a team!).

I'm running to raise money for Duchenne UK, a charity founded by families affected by Duchenne. They are driving pioneering research, accelerating access to life-changing treatments and giving hope to thousands of families living with this devastating condition.

The reality is that while progress is being made, there is still no cure. Every donation helps fund vital research and brings us one step closer to better treatments and, ultimately, a future free from Duchenne.

So whether you're donating because you care about the cause, because you know Oscar, or simply because you've enjoyed watching me stubbornly waddle my way around 13.1 miles for the last six years, I'd be hugely grateful for your support.

Every pound makes a difference. Every mile is for Oscar and the thousands of other boys and young men living with Duchenne.

Thank you for your continued generosity and encouragement. Together, we can help change the future for families affected by Duchenne.

Together, we will end Duchenne
