When: Sundays, 12 p.m. and Tuesdays, Thursdays, 5:30 p.m.
Polo + bikes = eco-friendly fun. Summer matches take place Tuesdays and Thursdays at 5:30 p.m. and Sundays at noon at 46th Street and Haverford Road — or, in case of inclement weather, at 12th Street and Pennsylvania Avenue. New players are invited to take part, as equipment is shared, but it also makes for a great spectator sport for the faint of heart. The friendly games offer another way to get some exercise without realizing it.
