I have friends who studied in UP Diliman who tell me that the Oblation run Is a revered tradition by the APO fraternity. The members consider it a privilege to run. Not everyone can participate in it. They do it to further a cause, to draw attention to an issue they support. The Oblation - the naked man with his arms outstretched - is UP's symbol, and because it is the university's symbol, the participants of the run emulate it. The Oblation, by itself means, "I have nothing but knowledge."
