02·Course by Section
A warm, saltwater swim in the protected waters of Subic Bay starting from the Boardwalk. The water is exceptionally calm but exceptionally warm, offering zero thermal relief before the long day ahead.
A fast but challenging ride utilizing the smooth concrete of the expressway and technical city streets, featuring a demanding climb up the SFEX. Wind and heat on the exposed highway can rapidly drain your energy reserves.
A flat but punishing run on highly exposed roads ending with a finish line run-in at Remy Field. With the heat index regularly climbing past 40°C, pacing and cooling are highly critical.
03·AVG beginners' Training Timeline
This 16-week progression prioritizes early aerobic durability before layering on strength work tailored for the SFEX highway climbs. The final phase focuses heavily on heat-tolerance training, ensuring your cardiovascular system is fully prepared to handle the extreme 40°C heat index waiting for you on the run.

With a heat index exceeding 40 degrees Celsius, execute a strict cooling protocol. Douse yourself with ice water at every single aid station, wear a white race kit, and keep your heart rate below your threshold to prevent overheating.
Target 80 to 90 grams of carbohydrates per hour, focusing heavily on liquid and gel formats. Consume 800 to 1000 milliliters of electrolyte-rich fluid per hour to offset the massive sweat rates caused by the intense tropical humidity.
Hold a conservative pace on the first half of the bike to preserve energy for the steep SFEX climbs. On the run, suppress your ego and run 15 to 20 seconds per kilometer slower than your standard target pace to manage the extreme thermal load.
Use deep-section wheels if the winds are light, but lower your tire pressure slightly if rain is forecast on the concrete streets. Pack separate gear bags for T1 at the Boardwalk and T2 at the SBECC, and walk the flow of both transition areas the day before.
The 1.2-mile (1.9 km) swim takes place in a highly protected bay where the water temperature is extremely warm, averaging around 84°F (29°C). Because of these high temperatures, you should prepare for a non-wetsuit swim. Focus your training on staying calm and pacing yourself conservatively in warm water.
This race utilizes a split-transition layout, with Transition 1 (T1) located at the Subic Bay Boardwalk and Transition 2 (T2) alongside the Finish Line at the Subic Bay Exhibition and Convention Center (SBECC) / Remy Field. To ensure a smooth race day, it is highly recommended to walk through both transition areas the day before the event to familiarize yourself with the flow. Booking accommodations within the Subic Bay Freeport Zone (SBFZ) will also make managing these two distinct locations much easier.
You should prepare for highly humid and hot conditions on June 7, 2026, with air temperatures ranging from a low of 79°F (26°C) to a high of 89°F (32°C). More importantly, the feels-like heat index frequently exceeds a grueling 104°F (40°C). Hydration, electrolyte replenishment, and pacing will be the most critical components of your race strategy.
You should trim your gearing specifically to handle the climbing sections on the Subic Freeport Expressway (SFEX). Additionally, if wet weather is forecasted for race day, slightly lower your tire pressure to improve traction on the technical city streets and smooth expressway concrete. These adjustments will keep you safe and efficient across the 56-mile (90 km) course.
The most convenient option is to fly directly into Clark International Airport (CRK), which is only a 45-to-60-minute drive to Subic Bay via the SCTEX. Alternatively, you can fly into Manila's Ninoy Aquino International Airport (MNL), though this will require a longer 2.5-to-3-hour drive to reach the venue. Booking your lodging within the Subic Bay Freeport Zone (SBFZ) will keep you close to both transition areas.
