Tristan Olij
pro triathlete & dutch national champion
Tristan Olij, born March 4, 1998, is a Dutch triathlete from Winkel, North Holland. Standing 1.88 meters tall, Tristan brings both power and endurance to long-distance racing. He discovered triathlon in 2015 after transitioning from motocross, shedding 25 kilograms in six months and quickly realizing his natural talent across swim, bike, and run.
Over the past years, Tristan has risen through the international field with standout results, including 6th at IRONMAN Italy Emilia Romagna (7:51:43) and 5th at IRONMAN Cairns (7:54:32). His top-15 finish at IRONMAN Cozumel and a strong showing at the IRONMAN World Championship in 2024 have established him as one of the most promising Dutch triathletes of his generation.
At GONNA, Tristan represents the next wave of endurance athletes: disciplined, resilient, and relentless in pursuit of progress. We’re proud to support him as he continues to push boundaries and build his career on the world stage.
