The Alpha Phi Omega (APO) fraternity members of University of the Philippines (UP) run again naked around the UP campus for the 34th Oblation Run.

The first oblation run was organized in 1977 at the University of the Philippines Diliman. It is an annual tradition of the said fraternity to promote a play Hubad na Bayani (Tagalog for Naked Hero). The name came from the Oblation, a statue of a nude man located in every University of the Philippines (UP) campus, which symbolizes “a selfless offering of one’s self to the country.”
The 2011 oblation run was themed “A Run for Philippine Rivers.” This one of the projects of the brotherhood in protecting the most popular river in the metro-Pasig River.
