Mobile medics go the extra mile

Long-distance running can be a hazardous business, however a group of altruistic Beijing doctors are making China's marathons are an altogether safer experience.

Going by the name of the Beijing Doctors Runners (BDR), these selfless mobile medics enter races around the country, interrupting their runs to come to the aid of ailing fellow participants, sometimes even saving their lives.

"We started the group because we realized lots of runners run with passion but not necessarily sensibly," said Zhu Xishan, the leader of the group and a doctor at Peking University First Hospital.
