I am performing a study realitve to the aspects of training and running a marathon. When we hit the wall, why do we have the mental desire to finish. From a psychological aspect what is occurring prior, during, and after a marathon??? I have participated in my first marathon, at the age of 42, this past fall. Have entered the Marine Corp Marathon for this year.

Any insight would greatly be appreciated.

Regards.
