The youngest athlete registered for the PyeongChang Olympics is 15-year-old Chinese halfpipe skier Wu Meng.
The oldest is 51-year-old Canadian curler Cheryl Bernard, who gained plenty of attention at the 2010 Vancouver Games. However, Bernard is an alternate for the Canadian women’s team, which means she might not compete.
If she doesn’t compete, then Finnish curler Tomi Rantamaeki, 49, would be the oldest competitor.
Bernard, who skipped Canada to silver in Vancouver, is likely to become the oldest female Winter Olympic medalist ever (surpassing one of her 2010 Olympic teammates) and the oldest of either gender since the first Winter Games in 1924.
