Medical experts run to the rescue

For a special group of runners, the "hell mode" BMW Hood to Coast China Relay offers both a chance to test their limits and help heal the wounded.

A growing number of altruistic Beijing physicians are becoming regular participants in all sorts of marathons, both as runners and health professionals safeguarding the rest of the field.

Going by the name of Beijing Doctors Runners (BDR), they kept watchful eyes on the Hood to Coast Relay for the second time on the weekend, although a quick-response medical team was already in place to provide aid when needed.
