Hi Amanda and welcome to BT! You couldn't be in a better place to share and learn about being a triathlete. You will find everyone here very helpful.
How long have you been doing triathlon? Do your parents or brothers/sisters triathlon? Have you done any races? What do you like best about triathlon? How long do you think it will take you to get to Kona?
Glad to see you interested so early good luck and train smart. I will recommend your get involved with a swim team as well as cross county and track at school good luck.
