Lei coaching on the cutting edge

As an Olympic champion fencer, China's Lei Sheng is accustomed to showing no fear when opponents come charging at him with a rapier.

Since retiring from competition a year after he capped his third Olympic Games with a gold medal in Rio in 2016, the 34-year-old Lei has demonstrated the same resolve in taking up coaching and helping 17-year-old Fu Yingying qualify for the Youth Olympics, which wrap up this week in Buenos Aires.

After a decorated career that includes three World Cup titles and top-three finishes across world and regional championships, Lei is reveling in his new role.
