Runners dress as gorillas for charity race through London
Runners donned full black gorilla suits as they took to the streets of London to raise money for charity.
Around 500 fancy dress-clad participants took on The Great Gorilla Run, now in its thirteenth year, which sees entrants tackle a five-mile (eight-km) course around the capital.
Money raised from the event helps fund the Gorilla Organization's work in Uganda, Rwanda and the Democratic Republic of Congo.
It has so far generated £2.4 million for gorilla conservation projects.
Jillian Miller, Gorilla Organization executive director, said: "As always, it's a real joy to see so many people coming together for gorillas, putting their suits on, dressing up and having a great time running, walking and jumping through the streets of London.
"But we have to remember that there is a serious message beneath the fun."
She added: " Events like The Great Gorilla Run help provide valuable support for frontline ranger patrols within the gorilla habitat, while also funding projects aimed at addressing the long-term threats such as habitat loss and poaching."
