Thousands of women are taking part in Race for Life events at Meridian Park in Cleethorpes and East Homes Field in Ilkley.
The Race for Life is the UK's largest women only fund-raising event. Since Race for Life began six million participants across the UK have raised over £457 million to fund the work of over 4,000 researchers, doctors and nurses dedicated to helping more people beat cancer.
Read about progress made in cancer research since Race for Life began in 1994.
Developments from cancer research have led to an overall drop of around 16% in the death rate from all cancers since Race for Life began.
– Emma Gilbert, Head of Race for Life
All women can embrace Race for Life whatever their age, fitness level or background to raise money for all cancers. Every two minutes someone in the UK is told they have cancer. It touches so many lives and the back signs worn by everyone taking part are a moving reminder to us all that women are taking part to celebrate lives that have been saved but also sadly lives that have been lost. We are asking women from across the country to unite, take part in the biggest fight against cancer this summer, and raise money for Cancer Research UK's life-saving work into all types of cancers, because it is 'all of us v cancer' and together we can help more people survive.”
