Lake Bonney Yacht Club hosts this race, situated on Lake Bonney Barmera instead of a road loop. Challenge Duathlon 2026 Race 4 is a Riverland Triathlon Club event, offering a run-bike-run format among participants familiar with the discipline, rather than a large-scale production.
The format is a standard duathlon: run, bike, run, with the transition being an active part of the event. Both Sprint and Enticer distances are available, under the series names “Duathlon Challenge Series Race 1 Sprint” and “Duathlon Challenge Series Race 1 Enticer.” The typical club atmosphere is expected at the yacht club: efficient, practical, and focused on racing.
