Sustrans people on bikes

Sustrans is the charity making it easier for people to walk and cycle. They are custodians of the National Cycle Network. A UK-wide network of signed paths and routes for walking, cycling and exploring outdoors. It connects people and places across the UK and provides traffic-free spaces for everyone to enjoy.

Sustrans works with volunteers, partners, and supporters to care for the National Cycle Network and encourage active travel choices (walking, cycling and scooting) for the school run and commute. They work with local authorities, policy-makers and communities to make walking and cycling a more attractive choice and to create healthier places that benefit us all.
