Russ Cook, from Worthing, West Sussex, was joined by supporters as he crossed the finish line in Ras Angela, Tunisia, the most northern point of the African continent on Sunday.

"It was good, I'm a bit tired," he told Sky News after taking a dip in the ocean.

He began his 16,000km (9,941 miles) journey in the most southern point, Cape Agulhas in South Africa, on 22 April 2023.

The 27-year-old had said he would become the first person to run the full length of Africa if he completed the challenge.

He has crossed 16 countries and run the distance of around 376 marathons.

One supporter, who ran some of the distance with Mr Cook, said: "The realisation that my wife got pregnant, had a baby and we now have a two-month-old in the time he's done this really put it into perspective."

He added: "It's left me speechless."

In the hours before completing the challenge, Mr Cook posted on the X social media platform: "Can't believe it's nearly over. See you at the shell garage soon boys & girls."

Mr Cook, who has raised more than £600,000 for two charities, has not just had the intense heat and physical exhaustion to contend with.

In Angola, he and his team were robbed at gunpoint. They had cameras, phones and passports stolen.

Then in August, he went missing and was separated from his supporters for days in the jungle in the Democratic Republic of the Congo.

They eventually managed to free him by paying off villagers who were armed with machetes.

In January, he turned to social media to help get a visa to cross the border from Mauritania into Algeria.

At the time, he said his challenge could end without the visa as there was "no other way" for him to reach the northern tip of Africa.

After a huge social media campaign, the Algerian Embassy said it would grant him a courtesy visa "on the spot", meaning he could cross the border.

For the final day of his challenge, Mr Cook invited his supporters to take on the last marathon with him.

Mr Cook also announced he will be throwing a finish line party to celebrate his achievements at a hotel in Bizerte, Tunisia.

The party is set to feature a performance by rock band Soft Play, formerly known as Slaves, comprising Laurie Vincent and Isaac Holman.

The money he has raised during the challenge, known as Project Africa, will be donated to The Running Charity, which supports the mental health of young people with complex needs or who are homeless, and Sandblast which educates people about Sahrawi culture.

Although the run across Africa was his biggest challenge, it wasn't his first.

At 22, Mr Cook ran from Asia to England, completing 71 marathons in 66 days.

He had only run the Brighton Marathon before he decided to run from Asia to England.
