Cycle to work!
Norwich is (relatively) flat, if you ignore gas hill, grapes hill or Kett's Hill!
Rediscover the truly invigorating and liberating experience of riding a bike and boost your health in the process. Figures show that about 42% of Britons own a bike. Whether you’re cycling to work, to school, to the shops or just for fun, the humble bicycle is an easy way to get more active.
Cycling to work is one of the easiest ways of fitting exercise into your day. It'll also save you money on petrol or public transport costs.
If you don’t have a bike, you may be able to get a cheap bike through the Cycle to Work scheme, or try your luck on Freecycle.
