About One Walk
One Walk is the world’s #1 fundraising event for families living with type 1 diabetes (T1D).
Together, we walk to power life‑changing research - improving life with T1D today and accelerating breakthroughs toward a cure.
What is One Walk?
At One Walk, you choose a family‑friendly 5km or 10km route and celebrate your fundraising success in a lively event village with lived‑experience speakers, activities for children and spaces to connect with others who truly understand life with T1D.
In the UK, One Walks take place across multiple cities in May - June 2026, bringing local communities together to walk, fundraise and celebrate impact.
One Walk is for everyone touched by T1D
Newly diagnosed / newly adjusting
Find families who’ve faced stubborn highs and sleepless nights - people who understand dose changes, CGM alarms and the courage it takes to keep going.
Your child will see other kids with pumps and sensors, run around together and feel that spark of belonging.
Lived with T1D for years
Reconnect with your community, share what you’ve learned and celebrate the progress your support has made possible.
T1D doesn’t hold you back.
Corporates, clubs, and community groups
When you’ve seen a colleague, classmate, or friend manage T1D at work, school or on the go, your support becomes a powerful acknowledgment of their strength.
Get together and come out to support and celebrate them.
Why your fundraising matters
T1D is relentless. It demands constant management, endless calculations and kit that can’t be left behind. For those living with it, and for the parents and carers who shoulder the daily burden, treat hypos and wake to midnight alarms, a cure would mean peace.
Over the last four decades Breakthrough T1D has helped transform life with T1D, but most people still face up to 180 additional health related decisions every day. But you can help us change that.
Research
Together, we are driving breakthroughs toward a world where no one lives with T1D. We focus on what the T1D community needs now and next, accelerating world-class international research and driving innovation forward.
Support
No one should face T1D alone. No matter where you are on your journey, our information can help you through diagnosis, understanding symptoms, and managing the condition to help you live a healthier and happier life/ live and thrive with T1D.
Advocacy
At Breakthrough T1D, we help make everyday life better for the people who face it. We believe that everybody who wants T1D technology should have it, and medicines should be easily accessible. We campaign to make this happen.
