Here are a few reasons:
well it really does not matter how fast you run in college as long as you dont be a loser and give up
suffer heat stroke if you run over 5 miles per hour............ dont run that fast !
They dont hop they run and they go pretty fast
I dont think there is a limit to the speed a human can run.
People do not run fast, at all, when compared to other runners in the animal kingdom.
Run As Fast As You Can or dont Go Near It At All
the height does effect how fast you run. people with shorter legs run faster than people with longer legs
Of course not!
dont take it so hard(do not run so fast)
Well, I feel like short people run fast becouse they have smaller legs, but people like usain bolt, which is pretty tall, runs extremely fast.. so i think its much about the technique and training when trying to run fast
its not how fast the rottweiler can run its how fast you can run !
dont download anything else or it will be even slower
