02·Course by Section
A warm-water, two-loop swim starting from the Boardwalk. Sightings can be challenging depending on morning glare, and the high water temperature will raise your core temperature early.
A fast but deceptive two-loop ride along the wide-open, fully exposed SCTEX highway. You will face rolling hills, minimal shade, and relentless headwinds on the return legs.
A flat, multi-loop run through the Freeport area under punishing midday sun. The concrete surfaces radiate heat, turning this final leg into a pure battle against dehydration.
03·AVG beginners' Training Timeline
This 24-week progression systematically prepares your body for the unique environmental stresses of Subic Bay. We build a deep aerobic engine first, transition into sustained strength to handle the rolling expressway, and dedicate the final block to heat acclimation and strategic tapering.
Aerobic Foundation
Build baseline endurance and joint durability with flat, steady-state volume.
Strength & Heat Prep
Introduce low-cadence climbing efforts and non-wetsuit swimming efficiency.
Specific Build
Replicate exposed SCTEX bike efforts and execute long, high-temperature brick workouts.
Acclimation & Taper
Execute specific heat-immersion protocols while systematically reducing training volume.
Adapts to your fitness, schedule & recovery every week.

With a heat index exceeding 38°C, cooling is your primary focus. Put ice under your tri-suit at every aid station, use cold sponges on your neck, and wear a white, highly breathable race kit.
Sweat rates will be exceptionally high. Aim for 800 to 1000 ml of fluid per hour loaded with 800 to 1000 mg of sodium, and maintain 80 to 90 grams of carbohydrates per hour primarily from liquid or gel sources.
Reduce your target power on the bike by 5 to 10 percent to prevent early heat stroke. On the run, execute a conservative run-walk strategy from kilometer one; do not chase pre-heat target paces.
Equip your bike with deep-section wheels, but be prepared for crosswinds on the expressway. Arrive in Subic Bay at least 5 to 7 days before the race to allow your body to naturally adapt to the tropical climate.
You can expect warm tropical water temperatures ranging from 28°C to 30°C (82°F to 86°F) for the swim in Subic Bay. Because of these high temperatures, the swim is strictly non-wetsuit for age-group athletes, so you should practice your swim pacing in a standard trisuit or swimskin.
The bike course features a mix of flat sections and rolling hills, primarily taking you onto the Subic-Clark-Tarlac Expressway (SCTEX). While the road surfaces are generally smooth, you must prepare for significant highway crosswinds and a hot, exposed ride with almost no shade. Pacing your effort and staying on top of your hydration during these windy stretches is critical for a strong run.
In June, Subic Bay experiences extreme tropical heat and high humidity, with daytime temperatures frequently climbing between 31°C and 34°C (88°F to 93°F). There is also a strong possibility of sudden monsoon rain showers or afternoon thunderstorms. Your training must prioritize heat acclimatization and a highly structured sweat-rate-tested hydration strategy.
The run course is predominantly flat and held on paved roads around the Subic Bay Freeport Zone, featuring multiple loops that offer great spectator support. However, the combination of midday heat, high humidity, and radiant heat from the asphalt makes it incredibly challenging. Success on this run depends on utilizing every aid station for ice, water, and core cooling.
It is highly recommended to arrive in Subic Bay at least 5 to 7 days before the race on June 7, 2026. This buffer allows your body to adjust to the intense tropical humidity, recover from international travel or jet lag, and complete a few crucial heat-adaptation workouts on the local roads.
