    Two British teachers have broken the world record for the longest journey in a tuk-tuk after pulling their failing vehicle for 43 miles. Richard Sears and Nick Gough traveled 37,500 kilometers around the world and passed through 37 countries. They did this to support grassroots education project in Africa, Asia and South America.

The pair, who set off from London, thought their expedition was over when the vehicle started to fail. When the tuk-tuk broke, they were only 70 kilometers from their destination. They decided to pull it the rest of the way. The tuk-tuk, which weighs 800 kilograms, was pulled in turns by Rich and Nick over three days. On arrival in Chepen, Peru, they discovered a mechanic who specialized in tuk-tuks and managed to fix it.

The pair were back on the road and aiming for their next goal. Along their journey they had to tackle deserts and jungles. They also survived close encounters with elephants in Uganda and Botswana and an accident in Malaysia. The greatest hardship on the tuk-tuk was the mountain ranges lying in their path, including the Alps, the Himalayas and the Andes.

Nick and Richard uncovered some inspirational projects across Africa, Asia and South America. They witnessed firsthand the educational challenges facing these areas today. They joined street children in the slums of Cairo, Khartoum, Kampala, Mumbai and Phnom Penh. They visited Congolese refugees (难民) in camps in Eastern Burundi. They witnessed how education could free sex-workers in Delhi and victims of human trafficking in Nepal.

The pair established The Tuk Tuk Educational Trust, a U.K. registered charity.

Talking bout their motivation, Richard said: “The world’s leaders have made a commitment to achieving universal primary education but, in spite of this pledge (誓言，承诺), over 57 million primary-aged children worldwide are still out of school; many more are in school, though still cannot access quality learning opportunities.”
