i have heard that a fit running back in the nfl should run at most a 4.3 or 4.4
An average time for a 14-year-old running the 50 meter dash is around 9 seconds. For a 100 meter dash, it would be about 13 seconds.
Under 2 minutes.
the average is about 34 seconds for a 11 year old girl
the average time should be 12-14. the good athlete will be running a 11.5 or under
The 40 yard dash times of running backs during the 2008 NFL Combine ranged from 4.24 (Chris Johnson) to 4.83 (Bernard Yvenson) with the average time sitting at 4.53.
the average time a sophmore runs the 40 yd dash is 4.7 that's average . there are a few that can run it in 4.6 or 4.5 by their sophmore yr but that's cause their really fast
4.5 seconds or lower
He ran a 4.24 the fastest time for a running back
