Where from Makati are you going? If you're on the District 1 area, Pat's route would be best I think. Or you can take Boni then Edsa-Santolan-Riverbanks-JPrizal-San Mateo then turn right to the street that says Mandala...you'll catch up with bikers and just ask around
But if you're on the District 2 area, take kalayaan cor C5 route...C5-libis-riverbanks-jprizal
hope I help..I'm not sure about the District thing..correct me if I'm wrong...Is District 2 area are Cembo, Comembo, East rembo, WEst rembo, Pembo area?
