The Western Melbourne Metropolitan Orienteering Series event at Rifle Range Drive / Kororoit Creek Road in Williamstown is one of several events run on Tuesday evenings.
Participants each receive a map with 20-25 pre-marked control points, and a card which is used to record the controls located. Controls are positioned on features such as light poles, fences, or trees. All participants start together, and must return to the finish within a designated time, or after locating a designated number of controls. It's up to you to decide which controls to go to.
