Microsoft founder, Bill Gates, has hailed Kunle Adeyanju, the Nigerian man who rode a bike from London to Lagos in a campaign to end polio.
Gates retweeted a story on the biker and wrote, “Incredible. #lionheart1759.”
Adeyanju had embarked on his transcontinental challenge in April to raise funds for Rotary International’s fight against polio.
The Nigerian covered more than 13,000 kilometres (8,000 miles) across 13 countries.
