Ok, first of all I know there is a similar question Here, but it is more related to muscle workout (if it's a duplicate please close that without problem)
I started run seriously in april, before that I trained myself in a bad bad way (few days and few kms), then the competition came and I barerly finished it...
After that I decided to be coached by a personal trainer, and from april to now I have done a lot of improvements.
In april 55' to run 10km now only 40'20", I'm very satisfied...
I had a very tough practice until these months even in the summer with 35° C, I did training 5 times a week, and during lastest week I was a little tired..
Now I finished a "period" of training and PT told me to rest for an entire week without a single run...
In my opinion is too much time, but probably I'm wrong and I think that only because I don't want to lose some of the improvements that I got until now...
EDIT: I spoke with my PT yesterday and he told me that I'll have two week for resting, first, as I said, completly without run, the second week only 3 workout 1) slow run 7km 2) medium run 6km 3) slow run 1km + fast run 4km
I think I'll die... :(
