Sustrans people on bikes

Sustrans is a UK sustainable transport charity. Their flagship project is the National Cycle Network, which has created over 14,000 miles of signed cycle routes throughout the UK, but about 70% of the network is on previously existing, mostly minor roads, in which motor traffic will be encountered.

Sustrans works with schools to encourage active travel (cycling, walking or scooting) among students. It also works with employers and local authorities. It administers several thousand volunteers who contribute their time to the charity in numerous ways, such as cleaning and maintaining the National Cycle Network, enhancing biodiversity along the routes, leading walks and rides and supporting communities to improve their air quality.
