The National Cycle Network is a system of cycling routes across the United Kingdom, designed to promote cycling for leisure and transportation. It connects cities, towns, and countryside, making it easier for cyclists to travel safely. The network includes both on-road and off-road paths, catering to various cycling abilities. Established by the charity Sustrans, the National Cycle Network aims to encourage more people to cycle by providing clear signage and well-maintained routes. It supports environmental sustainability and healthy living by offering an alternative to motorized transport, helping to reduce traffic congestion and pollution.
