I was impressed with Adam Ondra, a world ranked rock climber at age 11.
Then I saw video of Gisela Pulido, a World Champion in the booming sport of Kite Surfing at age 10, I believe. She was too young to compete in one World Championships, but won the other, KPWT (Kiteboard Professional World Tour), 2004, 2005.

A video of the wonder child from Spain is posted on YouTube. This kid takes some major air.
Kite Surfing is extremely difficult. I am very surprised Giselita could get so good at such a young age.
