This is a Populaire sanctioned by RUSA. As such (a) You must join RUSA to ride it, and (b) it is not a Western PA Bicycle Club ride per se. You sign up for it on the Pittsburgh Randonneurs website here: https://pittsburghrandonneurs.com/event/2023-100k-acp-populaire-03-18/

This route is an old favorite, riding mostly state roads from Monaca to New Middleton, OH, and back.
