Friends and families bearing torches lit up the night sky in southern Sheffield in a charity woodland walk attended by Jessica Ennis-Hill.
The Weston Park Hospital cancer charity’s Light the Night walk wound through ancient Ecclesall Woods, with more than 600 people taking part.
Olympic gold heptathlete Jess was the official starter for the event which followed a 4.5km route through the woods.
Walkers of all ages took part, many in memory of loved ones lost to cancer.
Jess said: “I’m proud as patron of Weston Park to be involved in such a fantastic event.
“The funds raised will go towards the amazing work they do for Sheffield people, which means a lot to me and the city as a whole.
“It was an honour to set off the night walkers, and it was good to see such an amazing turnout.”
Among those taking part were the French family from Stannington who raised more than £300.
Sam French, aged nine, who took part with his brothers Thomas, nine, and Daniel, 12, said: “It was cool walking in the woods in the dark watching the bats flying around us.
“There were people playing music on the way round and owls that lit up on the trees.
“We asked lots of people to sponsor me and my brothers to raise money for the patients at Weston Park.”
Also taking part were Sheffield boxers Scott Jenkins and Adam Etches, who are ambassadors of the charity.
Sarah Cross, fundraiser for Weston Park, said: “It was a truly magical evening. I’d like to say a huge thank you and congratulations to all the walkers who have made a remarkable contribution to Weston Park Hospital Cancer Charity with their fundraising efforts.”
Mark Allen, group director of sponsors Owlerton Stadium, said: “It was great to see so many people turn up to raise funds for this fantastic cause.”
