The games will run from Feb. 4-20, with the opening ceremony scheduled Feb. 4 at Beijing’s National Stadium, also known as the Bird’s Nest. Beijing — the first city to host both a summer and winter games — will reuse some of the 2008 venues for ice events. The suburb of Yanqing, home to part of the Great Wall, and the city of Zhangjiakou in neighboring Hebei province, will host events such as alpine skiing, snowboarding, cross country and ski jumping. Built for the games, a new high-speed rail line cuts travel time between the ski areas and Beijing to about 45 minutes. The Winter Paralympics will be held March 4-13.
