IRONMAN 70.3 Lapu Lapu
Sunday, 9 August 2026
IRONMAN 70.3 Lapu Lapu is a flat/fast 1.9 km swim + 90.2 km bike + 21.2 km run where hot air and a steady SW breeze mean pacing and hydration control matter as much as speed.
- 💧 Plan fluids toward 975 ml/h (cap near 1–1.2 L/h and let thirst be the ceiling). It typically runs hot through the afternoon.
- 🧂 Lift sodium to ~1250 mg/h.
- 🍚 Hold carbs at 80 g/h — heat slows carb absorption, so more isn't better.
- ⏱️ Sodium preload: ~500–750 ml with ~1,000 mg sodium, 60–90 min before the start.

Worlds qualification — slots TBAsee who qualified →Arrive early for a couple of short, easy warm-up efforts in the water (or pool/board warm-up if available), then settle into a steady rhythm before your wave moves. Get comfortable with the start flow: if you’re slower, stay slightly off the most crowded line and aim to be swimming straight early to avoid extra jostling. For the first few minutes, focus on controlled breathing and a consistent stroke rate rather than sprinting into traffic.
This is a 1,903 m freshwater swim with water temperature that varies, so treat the opening stretch as a “find your body” phase. Expect swimmers to spread quickly; settle into your lane/space and keep your sighting frequent to stay on line through any turns and avoid needless zig-zagging. Because the air can be hot later in the day, don’t overheat yourself in the water—stay efficient and calm, then build slightly only if conditions feel comfortable. Fueling is typically not the focus during the swim; save your calories and sodium plan for the bike where you can consistently take in fluids and carbs.
As you approach the final section, sight more often and shorten your strokes slightly to keep contact with the line. Get out efficiently: stand tall, clear the shoes/gear smoothly in transition flow, and focus on getting water off your legs and into your post-swim routine quickly.
Plan a smooth swim→bike flow: rack your bike where you can quickly find it, then prioritize a short, controlled dismount so you don’t lose balance grabbing things. In the first minutes, ride easy while you find rhythm—spend the time settling cadence and posture rather than forcing power. Have your fueling within easy reach before you fully commit, and start taking fluid immediately after you’re stable in your lane.
The bike is 90.2 km with 386 m of elevation gain and a flat/fast profile, so it’s built for steady output rather than repeated surges. With wind about 4.4 m/s from the SW, expect crosswind/headwind effects on certain legs of the course: keep your steering calm, stay relaxed in your shoulders, and use smooth power through gusts instead of fighting them. In hot conditions (air 25.6–30 C), your best performance lever is hydration: target the provided fueling per hour of 90 g carbs, 1000 mg sodium, and about 800 ml fluid, and start early so your stomach isn’t “catching up” later. Because the course is fast, you may feel tempted to push harder—stay controlled, keep your cadence smooth, and aim to finish the bike feeling like you can run hard, not like you’re surviving the final 20 km.
In the last segment, tighten your execution: take one final well-timed drink and carbs, keep power steady, and stay aerodynamic without tensing up. Be disciplined with your effort so your legs aren’t over-burned before you hit T2—your run success comes from arriving there intact.
For T2 (bike→run), expect your legs to feel heavy and “stiff” for the first few minutes—your job is to soften the first kilometer and let your stride come to you. Take a quick moment to organize: ensure your cap/sunglasses/shoes are set and you’re moving immediately. Start the run controlled—don’t carry bike speed into the first stretches; the hot air and prior pacing will decide how fast you can go later.
The run is 21.2 km with 28 m of elevation gain and a flat/fast profile, but heat changes everything when air is in the 25.6–30 C range. With wind still present from the SW, you may feel alternating relief and resistance—use it to regulate: if it’s into the wind, shorten stride slightly and keep breathing controlled; if it’s aided, avoid the urge to sprint. Keep your cadence efficient and stay tall rather than “chasing” speed early. Use your planned nutrition and hydration rhythm from the bike so you’re not trying to catch up; prioritize regular carbs and fluids to keep your pace steady through the middle and into the final kilometers.
As you near the end, look for a smooth form check: relaxed shoulders, steady breathing, and frequent small steps rather than big, tiring strides. The key takeaway is consistency—finish strong by holding effort rather than spiking pace too early.
Because conditions are typical but race-morning details can change, confirm any official guidance in the athlete guide on pacing adjustments, wetsuit ruling (set race morning if applicable), and course/wind updates.
