Race for Life on Sunday, June 20, is the UK's largest women-only fundraising event where all the money raised goes to fund Cancer Research UK's life-saving work.
Last year 2,500 women walked, jogged or ran the event which took place for the fourth time in the town and raised £133,000
Lisa Sweeting, Cancer Research UK's South West events manager, said: "This year Cancer Research UK's Race for Life is going to be full of amazing moments for everyone, from lining up at the start, side-by-side with thousands of other women, to the fantastic sense of achievement from crossing the finish line.
"Women of all ages, abilities, shapes and sizes take part take part in Race for Life. They motivate and inspire each other. Many simply walk round, chatting and having fun but they all share the wonderful atmosphere at the event."
Sherborne participants will be part of a total of 700,000 women taking part in more than 230 events across the UK between May and July. Cancer Research UK hopes that together they will raise a total of £60 million to fund the charity's life saving work.
