More than 8,000 women and girls took part in Race for Life in Dundee and Edinburgh.
The event held in the two cities on Sunday will raise money for research into 200 types of cancer.
In Dundee, four sisters who have all survived breast cancer started the Race for Life event at Camperdown Park.
Carole Bennett, Jane McCaffrey, 44, Ellen Ferrie, 38, and Susan Pyle, 43, joined Lord Provost Bob Duncan to set 1755 women on their way on the 5k route to raise money for Cancer Research UK’s pioneering work. The sisters also lost their mother to the disease in 2000.
In total, more than 2400 women took part in both 5k and 10k events in Dundee.
Mrs Bennett, 47, of Dundee, said: "What an amazing day it’s been. The atmosphere was electric and my sisters and I have had so much fun. We were also taking part in memory of our mum who died after being diagnosed with ovarian cancer. I know she would have been proud to know that we were doing our bit in the fight against cancer."
In Edinburgh the Race for Life event was started by guest of honour and breast cancer survivor Pamela Adams, 49, and her nine-year-old daughter Katie.
More than 5,700 women braved damp weather conditions to take part in 5K and 10K events at Holyrood Park, Edinburgh.
Race for Life spokeswoman Gillian Forsyth said: "I want to say a massive thank you to everyone who has taken part in Race for Life events.
"Cancer Research UK doesn’t receive any government funding for its life saving work so the money people raise through Race for Life is crucial to the charity being able to support the pioneering work of doctors, nurses and scientists who are fighting cancer on all fronts.
"In Scotland, the charity invests more than £30m every year in research, something which is only possible thanks to the generosity of the women who took part today, as well as to all those who sponsored them.
"Now the big day is over, we are asking our supporters to take one last step by returning the money they’ve raised so it can go into vital research to help more men, women and children survive cancer."
