In 2012, Original Propaganda Athletic Club opened its doors in Philadelphia with a simple conviction: every runner belongs. Founded to unite athletes across the entire spectrum, from beginners finding their footing to experienced marathoners chasing splits, OPAC built a culture where effort is respected regardless of pace or distance. Saturday mornings anchor the crew's rhythm, rotating through Philadelphia's parks and trails with pace groups that genuinely accommodate walkers through long-distance runners. The weekly tradition has become a proving ground for personal growth, skill development, and authentic connection. What drives OPAC's identity is the belief that running improvement and community support aren't competing values, they're inseparable. Over more than a decade, the crew has shaped how Philadelphia's athletic landscape values diversity and dedication, proving that a running community's strength lies in how it lifts up every single member.
