The Bay Run is a popular pathway that encircles much of Iron Cove and is located in the inner-western suburbs of Sydney, Australia. The Bay Run is particularly popular with joggers, walkers and cyclists who enjoy the pleasant waterside scenery whilst participating in exercise. It is approximately 7 kilometres long and passes through the suburbs of Rozelle, Lilyfield, Haberfield, Five Dock, Rodd Point, Russell Lea and Drummoyne. The Bay Run provides excellent views of Iron Cove for its entire course as it constantly hugs the shoreline. The Bay Run plays host to the annual Bay Run fun run, a community event that brings people together in the name of health, fun and exercise.
From the mouth of Iron Cove Creek at Timbrell Drive, Five Dock, The Bay Run follows the western shore of Iron Cove running parallel to Henley Marine Drive. The path is of good quality on this section as it has undergone significant upgrading in recent years. At Drummoyne, The Bay Run leaves Henley Marine Drive and traverses the Iron Cove Bridge, after which it turns right and follows the eastern shore of Iron Cove. Here it passes through King George Park and Callan Park in Lilyfield. After the Callan Park playing fields the path deteriorates to a dirt track but becomes sealed again at Leichhardt Park. The Bay Run continues through Leichhardt Park until it reaches the bridge over Hawthorne Canal where it turns right and parallels the City West Link Road at Haberfield. The Bay Run then continues along the foreshore of Iron Cove to the mouth of Iron Cove Creek where it completes its circuit.
