  Ed Jocelyn and Andy McEwen might have appeared to be a bit mad---the two set off on their own “Long March” through the remotest regions of China on October 16. The idea was to take a year to retrace one of the epic movements of modern military history.

The two British men in their mid-30s were working as editors in Beijing when they decided to reexperience the tales of the original marches. “We hold these people in such respect,” McEwen says.

They plan to keep diaries but will not share the contents during the trip. “When we get to the end we’ll put our heads together and try and come up with a book,” Jocelyn said.

Their trip has had some auspicious beginning, they have already met two Long March veterans(老战士) in less than a month of travel.

In this modern version, the pair are aided by high-tech equipment including a satellite phone, mini-computer, video camera and solar panels to recharge batteries. A mountain tent and portable stove will help them in the remoter stretches.

They plan to average 35-40 kilometers a day, and rest about every third day. Ed admitted that their trip would be very tough.

If they succeed, they will be the first foreigners to complete the entire Long March route since Otto Braun, the German military advisor who accompanied the Red Army on the Long March.
