Hong Kong: A fanatical runner jogged the equivalent of an ultra-marathon inside his small apartment as people in virus-hit China desperately try to keep fit while cooped up indoors. The country is at the centre of an outbreak of a new coronavirus, leaving more than 1,500 dead and sparking global alarm, but it is also in the grip of a health drive because the government is aggressively encouraging people to exercise to fight the disease.

With much of the 1.4 billion population ordered indoors and gyms closed, people are competing to outdo each other in how many bottles of water they can lift, how many push-ups they can do with their children on their backs or how many flights of stairs they can scale in their tower blocks. But Pan Shancu has easily won the unofficial gold medal, saying he jogged 66 kilometres (41 miles) in a loop at home in six hours, 41 minutes. He has the data tracker that he says proves it, and the 44-year-old's feat and a video of him repeatedly circling furniture in his apartment went viral in China.
