This August I'm taking on Breakthrough T1D's Sit Up Challenge, completing 1922 sit ups, 62 a day, celebrating the first big breakthrough in type 1 diabetes history. In 1922, insulin was first used to treat type 1 diabetes, proving for the first time that blood glucose could be managed and that living with the condition was possible.

This cause is deeply personal to my family. Two years ago, our lives were turned completely upside down when our youngest daughter was diagnosed with Type 1 diabetes at just 5 years old. Type 1 diabetes (T1D) is a lifelong autoimmune condition where the body cannot produce insulin, and it has nothing to do with diet or lifestyle. Suddenly, we had to face a frightening new reality.

Living with T1D is a relentless, never-ending job that never takes a day off. It means our minds are constantly at work, doing endless maths to calculate carbohydrate quantities, planning out every detail of the day, and carefully managing her routines just to keep her blood glucose levels safe and in target. It is a heavy, invisible weight that rests on our shoulders every minute.

Our daughter is so incredibly resilient, and she inspires me every day. But it breaks my heart that she has to carry this burden. She deserves to live her childhood and adolescence freely, without the constant worry of a chronic condition.

Finding a cure would mean lifting that weight. It would mean giving her back a life of freedom.

Breakthrough T1D is the world's leading charity funding the research to turn that hope into a reality. By sponsoring my 1,922 sit-ups this August, you are directly funding the next scientific breakthrough to treat, prevent, and ultimately cure Type 1 diabetes.

Every sit up celebrates that breakthrough and help fund the discoveries that come next. Research didn’t stop in 1922, and we won't stop until there’s a cure.

Every £25 could pay for an hour of research nurse support for someone involved in a clinical trial, which could ultimately lead to the next big breakthrough. Without this support there would be no trial.

Every £100 could pay for one person to be screened for type 1 diabetes, to help prevent undiagnosed complications and save lives.

Thank you so much for your support, your donations, and for helping me smash this challenge!
