I am 13 and i am always the fastest kid on all the sports I play i run a 7.4 60 yard dash the average between 7.7-8.8
There is no record time for the 50 yard dash by a 12 year old. The average time as of May 10, 2014 is 6-7 seconds.
6.0 is the average 40 yard dash time for a 16 year old girl. However, anything under 5.0 is considered to be very athletic and a superb timing.
I'm a 10 year old Girl and I ran a 6.0 in the 40 yard dash. I have proof to show.
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
A twelve year old should run the 50 yard dash in 7.4 to 8.2 seconds
