X-Adventure is the ultimate mix of triathlon and adventure racing featuring an ocean swim in the clear waters of Geographe Bay, trail run along the stunning granite coastline and mountain bike through the single tracks of Meelup Regional Park.


After the 2020 version of the event was cancelled earlier this year due to COVID-19, organisers Rapid Ascent are calling on triathlete and adventure racing enthusiasts along with Dunsborough locals to make up for lost time and get behind the 2021 event.


“We genuinely love what we do here at Rapid Ascent – conducting events that put smiles on people’s faces in some beautiful parts of the country,” said Sam Maffett, Rapid Ascent’s General Manager.


“To have had to cancel this fan-favourite event three weeks out from the 2020 race was devastating; not just for us as a business, but for the participants who put their heart and soul into training and planning their weekend away.


“We could not be happier to see events going ahead in Western Australia and we can’t wait to deliver an even bigger and better X-Adventure next April!” said Maffett.


Conducted in a friendly and welcoming race atmosphere, the weekend features five different off-road races attracting more than 1,500 competitors and many more spectators. Athletes of all abilities are welcome with a race to suit everyone.


Held over two days, the premier Long Course race is included in the 2021 Triathlon WA State Championships.


The X-Adventure Long Course includes 34 kilometres of action with a 1500m ocean swim, 12km trail run, and 20km mountain bike ride. The course attracts racers from corporate relay teams through to weekend warriors and elite athletes.


Frenchman, Simon Billeau, a renowned triathlete and multiple X-Adventure competitor has nothing but praise for the course. “This is a fantastic course, even though it is tough. It’s a great race in such a stunning location like Dunsborough. We are very lucky to have this race here,” Billeau said.


The weekend also includes a Short course option (700 metre ocean swim, 6km coastal trail run and 11km mountain bike), an Aquathlon-X  (1km swim, 5km trail run) event and other events designed especially for kids. This ensures sporting stars of tomorrow have a chance to join in the fun.


Located in the majesty of Geographe Bay, Dunsborough is renowned for its stunning coastal trails, beautiful blue water and awe-inspiring scenery. The courses stretch into the sacred Meelup Regional Park with all races taking in sculpted granite coastline, running tracks peaking with wildflower and free-flowing single-track for the mountain bike leg.
