But even Jake didn't want to try the madness of trying to run with 4 seconds less time than before for km, he would try to decrease 2 seconds per km to see what he could do, so the other day very early after Eva left to go to Jake's restaurant went to the race track at his house and Coach Davis arrived shortly after.
"Jake, I didn't approve of this because you can't understand what you're trying to do, we can say you're almost at the general limit of marathons if you decrease 1 second per km you have to decrease more than 42 seconds in a total time of racing."
"So, as you are in the elite of runners, you can manage to do that, what you have to understand is that 1 second less per km makes a lot of difference at the end of the marathon, which didn't make much difference before."
"What you are trying to do is run 4 seconds less per km and so you want to decrease your total running time by more than 168 seconds, this is very dangerous for you."
