The result marks her first IRONMAN Pro Series victory after a confident performance across the challenging Welsh course.
Following a strong swim, Lizzie stayed in contention throughout the bike leg before delivering an impressive run to move into the lead and claim victory in 4:23:56. She crossed the finish line just 15 seconds ahead of Anne-Sophie Pierre after an exciting battle that came down to the final kilometres.
"I can't really comprehend it - it feels amazing. I really wanted to win this race, and I'm so happy to come away with my first IRONMAN Pro Series victory," said Rayner after the race.
The victory is another major milestone in Lizzie's 2026 season and highlights her strength across all three disciplines. Racing aboard her Liv Avow, she executed a smart, consistent race to earn maximum IRONMAN Pro Series points.
