UP Oblation Run

The Oblation Run (sometimes referred to as Pylon Run or the Ritual Dance of the Brave) is an annual event held by the University of the Philippines (UP) and Polytechnic University of the Philippines (PUP) chapters of Alpha Phi Omega (APO) in the PUP and different UP campuses.

The runners are male, and traditionally run completely naked in public places, with their genitals fully visible, on a designated route. The event was first organized in 1977 at the University of the Philippines Diliman to promote Hubad na Bayani (Tagalog for Naked Hero), a film. It draws its name from the Oblation, a statue of a nude man located in every University of the Philippines campus, which symbolizes "a selfless offering of one's self to the country."
