If men did it, so did a dog!
A stray dog has completed a 1700km race after joining a cyclist race from Sichuan province in China to Tibet.
Nicknamed "Xiaosa", he joined the cyclists when one of them gave him food. Together with the athletes, he ran for 20 days, covering about 60km a day, and climbing 12 mountains.
Xiao Yong started blogging about Xiaosa's adventures, which had attracted about 40,000 fans by the end of the race. He now plans to adopt Xiaosa.
