Daughter wants to back out of ski club?

My daughter has stated over a few years her desire to join ski club. She is 10 years old. She has gone twice with me in the past, but it has been a few years. This year she also wanted to join and I did get to sign her up. It starts in two days and now says she doesnt want to go. She says the biggest reason is her fear to fail in front of her friends. I can understand, but how do I help her further on this to help build up her confidence. I dont have enough time now to take her on my own to help boost her confidence.
Any thoughts are appreciated.
