Medical staff at the Berlin marathon on Sunday saved the life of a heroin addict they mistook for a competitor. The head of the marathon's medical team said on Monday that some of his doctors came upon a man who had collapsed on a railway platform at the 37 kilometre mark of the marathon. The doctors resuscitated the 40-year old, who was wearing a numbered race bib. "It turned out he was a heroin addict," said Willi Heepe, who lead the team of 100 doctors on hand for the race. "He smelled of alcohol, but he was wearing running shoes. We thought he was a runner. The Berlin marathon probably saved his life," Heepe said.
