A dynamic and diverse field of athletes — from seasoned triathletes looking to sharpen their speed to enthusiastic first-timers venturing into the world of endurance sports — is gearing up for the much-anticipated Sunrise Sprint (S2) on Sunday in Subic Bay.

S2, a short-distance triathlon designed as an accessible entry point into the sport, features a 750-meter open-water swim, 20-kilometer bike ride, and a 5-km run. It will serve as a sub-event to the centerpiece Century Tuna IRONMAN 70.3 Subic Bay, also set for Sunday, following the IRONKIDS competition on Saturday.

The back-to-back events promise an explosive and inspiring weekend of multi-sport action.

More than just a race, the Sunrise Sprint plays a crucial role in developing future triathletes. Its Olympic-style course and shorter format make it ideal for athletes testing the waters of competitive triathlon while still providing a high-quality racing experience.

“The Sunrise Sprint is more than just a race — it’s a launchpad,” said Princess Galura, president and general manager of the organizing Sunrise Events Inc.

“It’s where tomorrow’s IRONMAN finishers get their start, learning the ropes, building confidence and discovering the joy of triathlon racing.”

She added that the format allows athletes to challenge themselves without being overwhelmed, bridging the gap between beginner-friendly races and long-distance endurance events.

“Whether you’re a first-time racer or a competitive athlete refining your form, S2 offers a space to grow, compete, and be inspired,” she added.

Muntinlupa City’s Lucienne Aragones, runner-up to Sofia Calvo in the most recent Sunrise Sprint event in Palawan, returns as a strong favorite in the women’s division.

She headlines a talent-rich roster that includes Rachelle Guieb, Katrina Bisuña, Veronica Pamintuan, Hanzel Barrameda, Gabriela Hirang, and others like Mariel Montebon, Shirra de Guia, Katrina Salazar, Isabelle Manlulo and Atheena Lopez.
