This a random post as I have just come across this website. My son is very interested in track and field and I have seen the AAU have a national meet for 5-6 year olds. I was thinking of what event he would be best at and he isn't real fast but loves running and playing tag at school. The kindergarten teacher says he is a natural runner. I was thinking about having him do the 400m race. What type of training should he be doing? Any advice would be greatly appreciated.
