She was the pre-race favorite, she led for nearly the entire day, and she certainly had to suffer through the final kilometers – but in the end, Kat Matthews has just secured victory at Ironman 70.3 Geelong. Facing a relentless pursuit from Grace Thek, Matthews had to dig incredibly deep in the closing stages, but she held just enough of a margin at the finish line to claim her second victory of the 2026 season.

Matthews is coming off a very recent appearance at Ironman New Zealand, a race she also won, but those miles were undoubtedly still heavy in her legs today. As a result, the finale of Ironman 70.3 Geelong became surprisingly tense, defying the comfortable lead many expected her to maintain.

The swim leg was led by Sophia Green, who headed toward transition after 23:13. She was followed 43 seconds later by Stephanie Clutterbuck, providing a momentary scare for spectators as Clutterbuck appeared to stagger and spin on her feet while exiting the water. Fortunately, she was able to continue. Matthews trailed by 1:29, surrounded by a group including Gabrielle Lumkes, Thek, Milan Agnew, Penny Slater, Jasmine Brown, Danielle Donaldson, and Charlotte McShane.

That grouping was short-lived. Once on the bike, Matthews immediately pulled away from the women she swam with, and within twenty minutes, she had closed the gap to Green. While Matthews may have expected to ride solo from that point, Green proved resilient, bravely hitching onto the pace and staying within contact for a significant portion of the ride.

Eventually, however, Green could no longer sustain the tempo. During the second half of the bike leg, Matthews finally managed to drop her. By the time she reached T2, Matthews had built a lead of 2:20. Grace Thek entered transition in third place, 4:17 back – and it soon became clear that she would be the one to give Matthews the most trouble.

The cracks didn’t show in the opening kilometers of the run, but during the second half of the half-marathon, Matthews began to visibly struggle. In contrast, Thek was pushing forward imperturbably, clawing back minutes with every split. With only five kilometers remaining, Thek had reduced the deficit to just 1:30, running approximately fifteen seconds per kilometer faster than Matthews. Thek smelled blood, and Matthews could surely feel her rival’s breath on her neck, making for a thrilling pursuit.

It became so close that Thek nearly pulled off the catch, but she ultimately ran out of real estate. Matthews crossed the line to win in 4:06:14, with Thek following a mere 36 seconds behind in 4:06:50 to take second place. In the closing stages it was Tamara Jewett who claimed third in 4:15:26.
