Is 16 too late to start ice dancing?

Ice dancing generally doesn't take decades to learn like singles skating does, because you're not learning triple jumps. Ice dancing is all about connecting with the music, strong edges & good footwork. Your ballet background will really help you with some of the moves. Lots of people have started skating in their teenage years and have gone on to some major competitions :) It's certainly not a waste of time, you can still be good at it even if you don't do it to compete.
