Duathlon course

Welcome to the Grampians Challenge Offroad Duathlon

We are excited to bring a new and spectacular course to enjoy views of the Northern Grampians and explore new trails, with a mix of gravel and 4wd trails and single tracks with some good uphills and breathtaking views.


4 km Run

35 km Mountain Bike

8 km Run


Start at Lake Wartook. The first run heads east along the Lake Wartook dam wall before u-turning and heading back and returning to the transition area. The mountain bike leg heads out along the eastern escarpment of the Grampians along primarily gravel tracks, the only exception a small section of asphalt. After looping back to near the bike start, the course follows a 4wd track down to the Zumsteins Picnic area where the transition area is located. The second run leg follows the MacKenzie River upstream past the Fish Falls and then the spectacular MacKenzie Falls before heading back to the finish at Lake Wartook.
