I'm 24 years old and just recently ran a timed 40 yard dash for the first time in 5 years. I'm 5'7, 160 Lbs and I ran it in 4.72. My goal is to reach 4.50. I'm 24 years old so my body has developed almost completely, your 12 years old so you will get faster as you get older!
Im sorry to say its not when i was in middle school we had big guys who could run it in a 5'6 to a 5'0 flat

Based on combine results from 2000-2017, the average speed of a Strong Safety in the 40 yard dash is 4.55 seconds.

40 yard dash/10 yard dash= 4 What ever the time you got for the ten yard, you multiple it by 4. It could be an average of your running time per 10 yard dash. Sometimes for several runners, they would feel worn out by the time when reaching the 40 yard mark.
5.2 4o yard dash
A 10 yard dash time is really not a good judge of your speed, the distance is too short. A 40 yard dash is what you need to get a good estimate of your abilities. but I'll give you time for both 40 yard dash-between 5-5.8 seconds 10 yard dash-between 1.3-1.5 seconds
4.40 TO 4.50
