Thousands of runners took part in the Race for Life in Stevenage, raising £150,000 for Cancer Research UK.
More than 3,500 people took part in the event on Sunday, July 7 at Fairlands Valley Park.
Runners could choose from the 3k, 5k or 10k race, alongside the Pretty Muddy obstacle course which was introduced in Stevenage for the first time this year.
Among those taking part was Sue Devereux, who has benefitted from Cancer Research UK's work when she received herceptin as part of her treatment for breast cancer, which finished nine months ago.
Sue said: "I lost my mum to cancer and I was diagnosed in 2022. I might not have survived this disease 20 years ago and in another 20 years it may be preventable.
"That’s why I take part with my friends."
Ava O'Connor took part as part of the 'Stevenage Startlets U9s' team just a few months after losing her dad, Cam Blake, to testicular cancer.
Her family's story featured on Channel 4's Super Surgeons, and the weekend of the race would have been her parents' seventh wedding anniversary.
June Brown, 86, from Cheshunt, has taken part in every Race for Life Stevenage has ever held.
After being treated for breast cancer earlier this year, she ran the 3k with her grandchildren Eden and Callum, who described her as a "fighter".
Sue Luck wore a picture of her partner on her T-shirt, after he passed away from leukaemia 15 months ago, just over a decade after losing her mum in 2011.
She ran with her daughter and her friend Emma Goldie and her daughter.
Sue said: "We’ve taken part in Race for Life to create better memories around what’s happened.
"It’s a good cause and needs to be supported because it’s crazy that one in two of us will get cancer."
Emma added: "My dad is living with cancer. We just want to try to get a cure for this horrible disease and every penny helps to make a difference."
All three races and Pretty Muddy will return to Stevenage on Sunday, July 6, 2025.
