IRONMAN Vitoria-Gasteiz

Arrive ready to move—get a short pre-start warm-up in and practice your first strokes so the moment you enter the water you can settle your cadence fast. Seed honestly and position yourself for clean water; if you start near the front or an aggressive cluster, spend the first minutes finding space rather than “winning” the first 50–200 m. The first few minutes should be controlled: lock into an even effort, keep your breathing consistent, and avoid hard surges as the field sorts out.

You’ll swim 3,812 m in freshwater where the temperature can vary, so treat the opening as an adjustment to conditions rather than forcing pace. With moderate air temps expected (14.7–26.6°C overall), the swim may feel smoother once you’re settled—focus on efficient form and calm breathing through the length. Drafting opportunities depend on start congestion, but your job is to swim straight when possible and keep your effort steady so your heart rate isn’t spiking right before the bike. Fueling on the swim is typically not the target—save your race nutrition for the bike where you can reliably absorb carbs and fluids at the planned rate.

Your T1 goal is speed plus organization: get your legs moving, find your rhythm immediately, and be deliberate with your gear so you’re not fumbling once you’re upright. As you mount, prioritize smooth pedal starts over power—transition from swimming stiffness into steady cadence. If you’re prone to going too hard early, set a calmer first 5–10 minutes and let the course and wind build your confidence.

Bike is 180 km with 833 m of elevation gain on a flat/fast profile—this is where you protect your plan while taking advantage of the speed potential. With wind around 5.2 m/s from the N, expect it to influence speed and effort more on open sections; keep your power effort consistent even if your speed fluctuates. Because this course is fast, the main risk is “feeling good” and overcooking the first half—stay disciplined and let the steadiness carry you through the elevation spread. Nutrition plan: target about 90 g carbs per hour, ~1,000 mg sodium per hour, and ~800 ml fluid per hour—start drinking and fueling early and keep it regular so you don’t play catch-up later in the day. If you feel any heat buildup (air temp can climb up toward 26.6°C), slightly bias toward extra fluid sipping within your fluid target rather than raising intensity to compensate.

In T2, focus on getting off the bike with good posture and quick turnover rather than trying to force speed immediately. Your legs may feel heavy right after mounting—aim to run tall for the first few minutes, settle into a sustainable rhythm, and let the heat and wind guide how hard you feel you can go. Think “controlled start, build as needed,” not “make up time instantly.”

The run is 42.2 km; with moderate heat expected (14.7–26.6°C), your key is pacing and hydration so you don’t fade late. Elevation gain isn’t provided, so treat the course as unknown on that front: start conservative and adjust based on how your breathing and legs respond rather than guessing from the day’s sensations. With a N wind component during the day, you may feel it changing how hard sections feel—use effort (breathing/heart rate) as your primary guide, not moment-to-moment pace. Keep fueling consistent using the same strategy you trained: sip and take carbs as provided/expected, and prioritize regular hydration early enough that you never get behind. If you’re building heat, don’t wait until you feel cooked—start managing by drinking more frequently within your overall plan.
