The location and course

X-Adventure is an event that will go straight to the memory bank as not only an awesome challenge, but also for the sheer beauty of the landscapes you race through.

Dunsborough on beautiful Geographe Bay, WA, is renowned for its stunning coastal trails, beautiful blue water and awe-inspiring scenery, and that’s why it’s the chosen spot for this spectacular off-road triathlon.

You’ll swim through the turquoise waters of one of Western Australia’s best beaches, run along a sculpted granite coastline interspersed with golden sand, and get to enjoy the roller coaster single track through fields of wildflowers and native grasstrees on your mountain bike.

“The course is amazing – a great swim, rock hopping along the coast, able to pick up a bit of speed on the trail run on the way back and then the mountain bike course just speaks for itself – it’s a mountain bikers dream with heaps of single track and twists and turns. I was smiling the whole way!” Ben Allen, X-Adventure Dunsborough Long Course Winner 2014 and 2015
