IRONMAN 70.3 Valencia

Arrive with a clear plan for calm positioning: in the first minutes, settle into your seed/pack, start easy, and focus on smooth breathing rather than early sprinting. Do a short warm-up in the water if possible, then line up with a conservative effort expectation for the first stretch so you can smoothly build once traffic opens. If you’re prone to getting boxed in, sight consistently and pick a line early to avoid weaving.

You’ll swim 1899 m in typical ~18°C water; confirm the official wetsuit ruling on race morning (it can be adjusted by the organizers). Expect conditions that reward efficient pacing—aim to stay steady through the main body rather than pushing hard against swimmers. If you feel wind or chop at the surface, shorten your stroke slightly and prioritize alignment and sighting to reduce drag. Fueling for the swim is minimal for most athletes—use this leg to set rhythm so you can absorb fluid and carbs immediately after you exit the water.

Treat T1 as a performance moment: get your legs organized, focus on a quick footwear/clothing transition, and take 1–2 controlled breaths before you stand or accelerate. Mount when ready and immediately settle into your planned cadence—on a rolling course, avoid chasing every rise with max effort. Have your first drink and carbs accessible and ready right away so you’re not “behind” for long once you start.

The bike is 90.2 km with 510 m elevation gain on rolling terrain, so your power/effort should be smoother than the road profile—let the downhills recover you and keep the uphills from turning into repeated surges. With wind from the NE at about 5.5 m/s, expect it to affect headwind sections and crosswind feel on turns/side exposure; stay slightly disciplined in your positioning so you’re not over-correcting. Fueling targets for the ride are 90 g carbs and about 750 mg sodium per hour, plus roughly 650 ml fluid per hour—take in consistently rather than waiting for when you “feel thirsty.” As the course undulates, adjust drink volume a bit if you’re sweating heavily, but keep the carbs and sodium cadence steady so your run doesn’t pay for missed fueling later.

In T2, think “compose first.” Your legs will feel heavy off the bike—do a brief transition jog/walk if needed to re-center breathing, then start the run at a pace that feels slightly easier than your target until you settle. Mentally cue a shorter first mile effort: on a flat/fast 21.5 km course, it’s easy to overcook early.

You’ll run 21.5 km with only 25 m elevation gain, so the course is designed for steady running and good forward momentum. Stay aware that the NE wind can still influence how steady you feel—especially when you have exposed stretches—so match effort to conditions rather than forcing pace if you’re getting pushed around. Keep fueling on the run with the same mindset as the bike: small, frequent intakes to maintain carbohydrate availability and hydration. Aim to stay on your fueling plan (carbs, sodium, and fluids) so you don’t “flatten” late; the flatter profile makes it easy to maintain rhythm if you’ve protected yourself with good fueling earlier. If you’re getting any stomach discomfort, reduce volume slightly while keeping carbs/sodium cadence as consistent as possible until it stabilizes.
