What activity does the Sustrans charity aim to promote through its national network of routes?

Sustrans is a well-known charity based in the UK that focuses on promoting sustainable transport options, particularly cycling and walking. It creates and maintains a national network of routes, such as the National Cycle Network, which provides safe and accessible pathways for cyclists and pedestrians. This initiative encourages people to choose active forms of travel, reducing reliance on motor vehicles and thus helping to alleviate traffic congestion and lower carbon emissions. By fostering an environment conducive to cycling and walking, Sustrans aims to improve public health, encourage outdoor activities, and contribute to a cleaner, greener environment.

The focus on cycling and walking aligns closely with the charity’s mission to offer practical alternatives to car travel, which is why this choice is the correct one. Given its efforts to develop nationwide pathways that facilitate these activities, other options related to running, driving, or boating do not align with the main objectives of Sustrans.
