Bird's eye view with 2x vertical exaggeration:
The Saturday 8km Course. (2pm)
Course on Garmin: http://connect.garmin.com/course/8309671
A flatter course without the qualification requirements of the longer Sunday runs. On the western side of Fyans Creek you'll be running on flat paths and trails. On the eastern side of the creek you'll experience undulating (ok small bumps that some will call hills) terrain amidst the bushland of the Grampians National Park.
The Saturday 2km Course. (1pm)
When it hits the bush it's a 'flat-ish' path with significant rocky sections. Out to Venus baths and back.
