IRONMAN 70.3 Davao Philippines

Get to the water early and do a short, progressive warm-up so your shoulders, hips, and breathing are calm before the start. Seed yourself based on your realistic pace—at 1.9 km, getting stuck behind slower swimmers costs time quickly. In the first few minutes, focus on clean exits and steady effort rather than sprinting for space; settle into a rhythm and start sighting consistently so you don’t drift. Near the exit, keep your stroke controlled through the final meters and prepare to transition smoothly into your wetsuit/gear plan (confirm the official ruling on race morning).

You’ll cover 1,945 m in open water at about 30.2°C, so the effort should feel more “endurance steady” than “cold-guarded.” Expect conditions typical for Davao—small chop and brief current-like effects can change how often you need to sight, so stay patient and make small course corrections. If the swim is wetsuit-optional, base your effort on feeling (comfortable cadence and relaxed breathing), not on chasing speed early; 1.9 km is long enough that going too hard in the first half burns you before the bike. Hydrate/fuel during the swim isn’t practical for most athletes here, so your plan is to exit sharp, start the bike quickly, and begin your fueling as soon as you’re safely rolling out of T1.

Your T1 should be about speed with control: get out of the wetsuit/gear cleanly, secure helmet and shoes, and make your first pedaling attempts smooth. As you mount, prioritize balance and cadence for the first few minutes—don’t force watts until you’re fully upright and stable. Because this course is flat/fast (90.4 km, 214 m gain), set your effort to sustainable power right away so you’re not chasing speed on early stretches. Use the first section to get into your fueling rhythm before the long “go” sections start feeling easy.

The bike is 90.4 km with 214 m of elevation on a flat/fast profile, so the aerodynamic and pacing discipline matter as much as strength. With wind around 2.6 m/s from the S, plan for subtle cross/head/tail effects—hold your line, stay smooth through gusts, and avoid surging when you feel the wind help. Because the course is fast, it’s tempting to overcook early; instead, keep a consistent target effort and use the rolling moments to stay aerodynamic and efficient rather than to sprint. For fueling, aim to take in about 90 g carbs per hour, 1,000 mg sodium per hour, and around 800 ml fluid per hour—start early enough that you’re never “behind,” and take it consistently rather than in large late grabs.

In T2, focus on getting your legs under you quickly without forcing the first strides—after 90.4 km, the first 1–2 km is about finding that bike-to-run gear-change. Keep steps light and cadence quick enough to avoid jamming your quads; the run is 21 km flat/fast (60 m gain), so it rewards efficient mechanics. Start hydrating early and mentally commit to fueling on time—late running catches up fast in heat. If your stomach is sensitive, simplify: stick to the same intake you practiced and don’t try to ‘fix it’ mid-race.

You’ll run 21 km with a relatively flat/fast profile and only 60 m elevation gain, which makes pacing and heat management the main challenge. Air temperatures are typically hot (about 23.4°C up to 29.7°C), so expect earlier body temperature rise and plan to regulate effort rather than race each mile by feel. Use the wind (2.6 m/s from the S) as a cue for pacing—when it’s in your face, hold back slightly; when it helps, you can maintain form and not drift into an unplanned surge. Continue fueling consistently in the heat and keep fluids coming—your bike-target intake rhythm should transition into regular small takes rather than waiting until you’re thirsty.
