[5] In 1950, professional scouter Sol George Levy, an APO member from the University of Washington in Seattle, went to the Philippines to generate interest in the scouting movement in the country.

Levy invited scouts in Manila to a conference, where he proposed that a scouting-based service fraternity be established in the country and distributed APO publications to the audience.

[2] A group of scouts led by Ibrado I. Ureta from the Far Eastern University were particularly interested, and on March 2, 1950, he and 20 others established the first organization of APO outside of the United States, now known as the Alpha Chapter.

[7] On September 22, 1975, four members of the APO Alpha Delta chapter in San Sebastian College – Recoletos established the Scouts Royale Brotherhood (SRB), a fraternity exclusively for high school students.

SRB was initially intended to be the youth arm of APO, as both fraternities share the same traditions, core principles, motto, colors, and symbols.

The run is named after the Oblation statue, which depicts a naked man facing upwards with arms outstretched to symbolize selfless devotion.
