Grampians National Park hosts the 80 kilometre endurance event every June long weekend.

Course convenor Doug Craig said the course changed every year to maximise the “breathtaking” Grampians scenery and to offer a new challenge for the event’s return teams.

Mr Craig described parts of this year’s course as new and other parts old.

“Over two days teams battle the terrain and pit themselves against the elements as they hike, run or scramble through the course of roughly marathon distance,” he said. 

“There will be on and off track sections through the bush, 4wd tracks and private land sections as well as long climbs to great views, before one of the prettiest finishes ever.”

Recipient of The Southern Grampians Event of the Year award, Serra Terror 2017 sold out within 15 days.

The course will begin at Dunkeld at sunrise, move up and down the mountains, through red gum clearings and if wet, necessitate wading into wetlands.

There will be hiking along ridgelines and more mountainous terrain before reaching the finish at Sarah and Tom Guthrie’s Grampians Estate at Thermopylae near Mafeking.

Teams could enter as a four person endurance team attempting to complete the entire course, or as a relay team of five to eight members, interchanging at checkpoints along the course.

Dunkeld Community Centre will host a pre-event briefing on Friday evening at 6-7.30pm to inform team members and support crews on final arrangements and safety aspects.
