One of the most comprehensive studies into the effect of cycling into health and disease in the UK is looking for your help.

Researchers at University College London are about to begin research in collaboration with the CTC into how riding your bike regularly affects your risk of heart disease, stroke and cancer.

It will aim to find out if a particular amount, or intensity of exercise is most effective in warding off disease. People's cycling fitness will be compared against their overall health.

All regular cyclists are invited to take part, and for the purposes of this study, 'regular' means at least once a month.

The questionnaire here assesses your cycling fitness and overall heallth, and all the information will be held anonymously by UCL.

These are some of the important questions that you could be helping scientists to understand:

• How much cycling is necessary to reduce the risk of disease such as stroke, diabetes and cancer?
• What level of fitness is associated with reduced health risk?
• Who benefits the most from cycling?

The survey takes 5-10 minutes to complete and could win you £100 in cycling vouchers.
