One Walk Your Way

Want to walk somewhere special? Choose your own route, date and distance and create a One Walk that works for you. Walk with family, friends, colleagues while raising funds to support our mission.

Why take part?

  • Walk for someone you love: Show your support for a child, friend, partner, parent or family member living with T1D.
  • Meet people who understand: Connect with others who understand the realities of life with T1D.
  • Raise funds that change lives: Every pound raised helps us fund research, improve treatments, campaign for change and move closer to cures.
  • Be part of something bigger: Join a community united by one goal: creating a world without T1D.

Why your support matters

T1D affects over 400,000 people in the UK.

It’s relentless. Every day brings decisions, calculations and challenges that never fully switch off. The impact reaches far beyond blood glucose levels, affecting families, relationships, confidence and everyday life.

Together, we’re funding research, driving progress and moving closer to a world without T1D.

Locations coming soon

We’re currently planning our 2027 One Walk events and Community One Walk locations.
