XTERRA Dunsborough Australia has opened entries for its 2024 world-class races and will again be held in the south-west coastal town of Dunsborough, Western Australia on April 20-21, 2024.

Featuring six off-road races that include qualifying spots to the 2024 XTERRA World Championship in Trentino, Italy; the 2024 Triathlon WA off-road State Championships; and two new XTERRA Trail Runs – this is world-class racing in a world-class location.

Proudly conducted by Rapid Ascent; in 2023 a groundbreaking partnership was formed with XTERRA Global, propelling the event to even greater heights. This event has already cemented its reputation as Australia’s largest off-road triathlon (formally held as X-Adventure), and showcases a spectacular course of ocean swimming, mountain biking and trail running.

The premier XTERRA Full Distance race consists of a 1.5K swim in the turquoise waters of Geographe Bay, followed by a 28K mountain bike race through the flowing singletrack in Meelup Regional Park, and finishes with a 10K trail run along the sculptured granite coastline.

2023 XTERRA Full Distance winner Sam Osborne (NZ) said the course lived up to its’ expectations with a technical run and an excellent mountain bike leg which is what attracted him to the Dunsborough race in the first place.

“It’s honestly a banger of a race on a course [that] really rewards somebody who can rail a bike around a corner,” said Osborne.

Elite competitors from all over the world will race for a share of the $12,000 AUD ($7500 USD) cash prize pool; whilst age-groupers will have the chance to secure one of the 28 age-group qualifying spots into the 2024 XTERRA World Championship.

XTERRA have added two new trail runs to the 2024 event program with 21K and 10K stand-alone events set to capture the beauty and diversity of the Meelup Regional Park hinterland and coastline.

The 21K race acts as an official qualifying event for the 2024 XTERRA Trail Run World Championship allowing competitors to be part of XTERRA’s global series and ranking system.

Conducted in a friendly and welcoming atmosphere, the event weekend also features a Short Distance triathlon (750M swim, 15K mountain bike, 6K trail run), and adventure races just for kids.

The off-road races are open to individual athletes or relay teams of up to 3 doing one leg each where mates can get together and join the 1,500 competitors who tackle this event each year.
