Thousands of women came together today to take part in the annual Race for Life at the Norfolk Showground.
Over the next three months, they will be joined by many thousands of others who are determined to help beat cancer and run, jog, or walk in honour of their loved ones.
Race for Life started as a single event in 1994 at Battersea Park in London with 680 participants.
Since then, 7.1 million participants across the UK have raised more than £526 million to fund Cancer Research UK's vital work.
Victoria Leggett reports.
