40-yard dash time for a 14 year old?

Question

I am 14 years old and in 8th grade, I am 6'2 and weight 150 pounds
I am a WR and I run a 5.1 40 yard dash
Is this fast for a white kid and for my age, height and weight?

And how can I improve my acceleration speed from the first 10 yards?

Answer 1

thats pretty good, im 13years old, 5'6, 130 pounds, i run a 40yrd in 5.4sec...

to improve your speed pop off every step and absorb the shock

also make a 90 degree angle with your arms and swing them parallel as your running

Answer 2

4.6 is flat out good.... but remember...don't get caught up in 40 times...when on a football field is someone going to run a straight line. Even a wide receiver on a vertical route has to get by the DB. Don't forget about quick feet as they will take you along way on a football field. But if you are 15 and run a 4.6 pretty dang good.
