EXSS X-TRI Off Road Triathlon & Duathlon

EXSS X-TRI is an off-road multisport event at Lake Leschenaultia in Chidlow that offers cross triathlon and cross duathlon formats with long and short course options. The long course triathlon holds WA Triathlon State Championship status and World Triathlon World Championship Qualifying Event status for off-road triathlon. The long course duathlon is an Australian Off Road Duathlon Championship event and a WQE.

The swim takes place in the lake's freshwater. The mountain bike leg uses purpose-built single track with jumps and alternate, less technical lines through Western Australian bushland. The run follows the Lake Loop Run trail around the lake. Courses are lap-based so participants pass spectator areas multiple times. An aid station is available on the run course.

Results are provided by WASE TIMING with live results and splits. Medals are awarded to the first three athletes in each category, male and female. Prize money is provided for top finishers in the long course event and for top non-member finishers in the All Comers classification; winners must be present to receive prize money. Race day competition rules include no passing on the left, no littering, and expectations of sportsmanship.
