(UPDATE) ONE week into the highly anticipated Century Tuna Ironman Philippines and the IM 70.3 Subic Bay, contenders are honing their skills for a race filled with challenges, not only prepared to test their power, speed and stamina but also to employ strategies crucial for victory in these premier endurance races.

The race, headlined by a diverse field of runners with varying strengths, united by a common mission in different age-group divisions, will be a unique battle of participation and collaboration. It is the only event that features both the full-distance (3.8km swim, 180km bike and 42.2km run) and half Ironman races (1.9km swim, 90km bike and 21.1km run).

"We've maintained the two-loop swim course but have made some adjustments," said race director Neville Manaois. Lane lines have been removed and replaced with color-coded buoys marking the route every 50 meters — yellow for the outbound path (yellow), red for turning points and orange for guide back.

The bike course is divided into two parts. The first part, starting at Subic-Clark-Tarlac Expressway, is a two-loop (45km) segment covering a total of 90km. The second 90km of the full-distance event is new, requiring athletes to complete six loops in Subic Bay.

This section leads participants through Argonaut, NCT road, and San Bernardo Road, offering a challenging and fast-paced race. Given the multi-loop course, athletes are recommended to use GPS devices to track their distance and laps. Organizers will provide hydration, food and access to personal need bags.

The run stage remains unchanged from last year, featuring a rolling, fast route. The four-loop course includes aid stations providing hydration, food, and medical services. Lap bands are provided to help athletes oriented during the race.
