PLEASE NOTE: Due to recent Development Victoria works around the Pit lane buildings ALL events will start on Aughtie Drive / Pit Lane area. You may have seen early flyers promoting the event showing new start lines for the Brooks 10km Main and the 5km Main in the parkland behind the Pit Buildings. That will no longer be the case. Half Marathon Slower Participants should also note that we've had to change the Alternative last lap route as well. See FAQs, A-Z, S for Slower Participants. . Run Prix is organized by Big Long Run Pty Ltd.    Contact Us.
