Women of all ages donned their brightest pink clothing and their trainers to help raise money in the battle against cancer.
Hundreds of women – along with a few young boys, dogs and toddlers – took part in Race for Life in Doncaster.
Organisers estimate that around 1,000 people ran, jogged or walked the 5km route at Town Fields.
Once all their sponsorship money is collected together, it is hoped that around £100,000 will have been raised for Cancer Research UK.
Diane Schofield, aged 50, from Adwick, was taking part for the first time.
She said: “I wanted to take part because I turned 50 a couple of weeks ago and know people who have had cancer. I am running for everyone past and present who are fighting or who have fought this terrible disease.”
Sharon Smith, 36, from Thorne, ran with friend Amanda Saxton, 35, of Moorends.
Sharon said: “I’m doing it for my mum who is currently fighting cancer and my auntie Pauline who we lost.
“When I went with my mum to chemotherapy and saw the amount of people that you see hooked up to drips it really brings it home to you how many people are affected.”
