Since 2017, WCU has had a rivalry with fellow Pennsylvania side Philadelphia Lone Star FC, which also joined the NPSL in 2017. Both teams' first league match was against one-another and made the first leg of a derby, the Route 3 Derby, with the winner after both legs being awarded the Kildare's Cup.[5] West Chester has won the cup every year of its existence, with the closest series coming in 2019 when United won 4–3 after initially losing the first game for the first time.[6][7]
