Road cycling, the most common form of cycling, is simply
riding a bike outside for exercise, sport or to get from A to B. Track cycling
adds a competitive element and sees riders race around a specialist track at
high speeds.
Just hop on a bike and you're good to go. British Cycling, Scottish Cycling, Welsh Cycling and Cycle NI have
information about clubs and racing tracks, and the Breeze programme for women cyclists offers a range of safe and
sociable cycle routes for all abilities. If you don't have access to a bike
there are hundreds of bike rental facilities across the UK.
