40 yard dash for a 8th grade running back?

Question

I am 13 yrs old, play running back and got a 4.95 on the 40 yard dash. is that good?

Answer 1

 thats a very good time for your age. all these kids saying they can run a 4.5 as a 13 year olds is bullshit.

Answer 2

you gotta a put up some speed, when i was 13 i ran a 4.43

Answer 3

No that's not so good, I play tuning back  and I run 4.55. Try leg pressing or jogging/ sprinting weights ii use 25lb weights but the weight can vary.ps:I'm 13too

Answer 4

Nah man you are slow. I am 13 years old and can run a 4.69. No offense, but your team must suck since you are there running back and only run a 4.7. Try squatting, and you might get it down a little.
