lonely dog a bite to eat and it didn't look back

Xiao Sa just ran up the mountains or along dirt roads.

'Many people stopped cycling in some sections, then took the bus, but the dog made it,' he said.



Zhang put the dog on the back of the bike when the team was riding downhill.



'The speed can reach 43 miles per hour, impossible for the dog to catch us.'

Back on the road again: The dog and his friends have built up a massive following online after word got out about their trip

Then word began to spread of the cyclist and the homeless dog.



Wang Penghao, 24, from Jiuzhaigou, Sichuan province, said: 'I've heard about her from other friends who rode to Lhasa on the road before I met her.



'They told meto take care of her if I saw her, and give her some food and water like they did.



'She followed us for three days, running behind our team but sometimes leading us. She's very smart and knows the route, because she never got lost even when we passed through mountains.'



After following Wang, the dog lagged behind and met another cyclist, Wang Zi, on May 4.



'She may be the first dog who ran to Lhasa along this route,' said Wang Zi, who was followed by the dog one day.

'I have a special feeling about her, especially when I found she was never lost, waited for us at milestones on the road, and ran all the time, making me feel that she never feels tired,' he said.



Wang Zi will continue
