What is an average 40 yard dash time for a 93 lb. nine year old?
Don’t worry about it yet. It doesn’t matter right now. You’re only 9 years old. Just work on your form. I ran a 4.59 in high school and give a lot of credit to it because of form. I was fit of course and played running back. Learn how to sprint and stride. BTW that Michael Jackson comment was pretty funny. RIP.
