Oh! Yes it is!

In fact it is.  Since I started to run, I realized how peaceful I felt after it.  Since the moment I start running, my mind is in blank completely.  I stop thinking, I just see the landscape and listen to the nature noises.  I use this activity to relax.  When I feel I'm under stress, I wear my sport clothes and start running.  It is incredible how after doing it, my energy comes back to me!  I really recommend it, it is costless!
