The findings are very clear that creating new walking and cycling routes or improving existing routes will support physical activity in groups for which exercise can fall below the recommended levels. This includes supporting physical activity among older people, people living in deprived areas and people living with a disability or long-term illness. A further important finding is that when walking and cycling routes are built or improved in areas where levels of walking and cycling are low, relative increases in levels of physical activity can be large
