The RAC Karri Valley Triathlon showcases the beauty of WA’s South West whilst providing triathletes with a unique racing experience.

After swimming in the clean, fresh waters of Lake Beedelup you will be challenged by the undulating bike course under the canopy of the Karri Forest, and soak up the majestic views and natural charm of the RAC Karri Valley Resort and surrounds during the road/trail run.
