Under a new “Winter Sunshine Sports” scheme, Chinese primary school children will have to run one kilometre, junior students will run one-and-a-half, while high school and university students will run two. The programme kicks off on October 26 and students are expected to have to complete their runs in their break times. The sports departments of provincial governments will enforce the scheme, which will continue until the end of April. Schools will arrange where the students can run, but races along busy roads will not be allowed. The government is concerned by a rapid increase in child obesity after a report last year from the Health ministry showed that urban six-year-old boys are 2.5 inches taller and 6.6 pounds heavier on average than 30 years ago.
