What is the main conflict in The Loneliness of the Long-distance Runner by Alan Sillitoe?

Smith is the protagonist and narrator of this, the longest story in the collection. He stole money from a baker and was sentence to spend a couple of years in Borstal, a prison for juvenile delinquents. He has agreed to train in order to compete in the annual long-distance running championship held between the various boys' homes. These morning training sessions allow Smith a reprieve from the cramped confines and menial tasks of the boys' home, and also allow him to collect his thoughts. During these sessions, he has decided to buck the establishment and essentially throw the long-distance championship race, as a way to get back at the governor (the headmaster of Borstal) and show everyone he cannot be changed or rehabilitated.
