The Rickshaw (人力车) Run is one of the world’s most unusual races. It lasts for two weeks and takes place in India. Each team has one rickshaw and one to four drivers. The rickshaw has to transport light loads (货物) in short distance, which makes the event such a challenge.

The race takes place twice a year: once in summer and once in winter. The route (路线) is different, but the length is always about 2,500 kilometers long. The race is a lot of fun, but it also has a task for all participants (参赛者). They should raise at least 1,000 pounds for charity.

The first race took place in 2006 with 34 teams. Since then, the Rickshaw Run has become famous around the world. A few days before the race, if participants don’t know how to drive a rickshaw, they will receive a crash course to make sure they can control it during the race. They can also use the pre-race time to decorate their rickshaws and ask any last-minute question.

“The adventure really starts when things go wrong,” said one participant. “The wind blew a hole in our rickshaw, but I saw the most beautiful town in India!” said another. Just as the organizers say on their website, “There’s no set route, and you don’t know if you’re going to make it. The only certainty is that you will get lost, you will get stuck and you will break down.”

Are you ready for some real adventures?
