Record-Breaking Day in Santa Cruz: Two Athletes Shatter Course Records at Ironman 70.3
On Sunday, September 8th, 2025, the triathlon world witnessed a historic day in Santa Cruz. For the first time, both the men's and women's course records were shattered on the same day at the Ironman 70.3 Santa Cruz. Sam Appleton and Tamara Jewett delivered performances that not only redefined the limits of endurance racing but also solidified Santa Cruz's reputation as a premier destination for world-class triathletes.
Men's Race: Sam Appleton's Strategic Masterpiece
Record Time: 3:41:04
Sam Appleton's victory was a masterclass in tactical racing and superior run fitness. Hailing from Sydney, Australia, and training in Boulder, Colorado, Appleton executed a patient strategy that paid off when it mattered most.
Breaking Down the Performance
- Swim (1.2 miles): 22:45 - Emerging 3rd from the water
- Bike (56 miles): 2:01:39 - Maintaining 2nd place
- Run (13.1 miles): 1:12:23 - 4th fastest, yet enough to clinch victory
Appleton's performance was remarkable not for the fastest splits but for his ability to maintain a balanced approach across all three disciplines. His smart positioning throughout the race proved to be the winning formula.
The Competition Behind Him
The depth of talent made Appleton's victory even more impressive:
- Trevor Foley finished second in 3:42:52. Despite posting the second-fastest run split (1:11:31) and a solid bike split (2:02:32), his 19th-place swim finish (24:12) created a deficit too large to overcome. The 1:27 gap he gave away in the water proved decisive.
- Ben Kanute rounded out the podium in third place (3:43:06), with similar swim and bike splits to Appleton but losing crucial time on the run (1:14:26).
Women's Race: Tamara Jewett's Dominant Display
Record Time: 4:10:54
Tamara Jewett's victory was a showcase of local preparation and superior run fitness. The Canadian athlete's decision to train with Santa Cruz Masters to familiarize herself with the swim course was just one element of her comprehensive race strategy.
The Jewett Strategy
- Swim (1.2 miles): 26:42 - 5th place, staying within striking distance
- Bike (56 miles): 2:21:38 - 7th place, conserving energy for the run
- Run (13.1 miles): 1:17:34 - Dominant 1st place by over 4 minutes
Run Dominance
Jewett's exceptional run was the key to her record-breaking performance. Her 1:17:34 half-marathon created a decisive gap that no competitor could bridge, demonstrating the level of fitness and race strategy that sets elite athletes apart.
- Jackie Hering of Cottage Grove, Wisconsin, finished second in 4:12:43.
- Grace Alexander of Atlanta claimed third in 4:16:33.
What These Records Mean for Santa Cruz
