The Afterwork Navigation League event at Belmont Regional Park is one of a series of 3 hour rogaines in the evenings. These were initially designed as practice for longer events, but are perfectly good as ends in themselves.
The event is 100% off-road, hills, bush, farm, views (weather dependent), great tracks and a few streams. Start/finish is at the Belmont woolshed at the end of Stratton St.
These events are usually 3 hours, but occasionally might be shorter. Maps are available from 5:20pm, briefing 5:50pm, and rogaine from 6pm to 9pm. For locations further out these might be half an hour later. If you can't get there by then why worry - just rogaine for a shorter time. In fact if you want a shorter period tell the organiser and just do it!
