IRONMAN 70.3 Elsinore

Arrive early to get a quick feel for the water and your start pace. Because you’re seeded, plan to start in a position that matches your swim speed so you can settle within the first few minutes rather than fighting for space. In the first strokes, focus on calm breathing and efficient body line; avoid going hard before the field starts to space out.

You’ll swim 1,900m in water around 18.8°C, and the official wetsuit decision is set on race morning—confirm in the IRONMAN athlete guide. With typical air conditions starting cool and warming later (14.4–22°C), keep your breathing smooth through the first buoy-to-buoy section and don’t over-grip the first turns. Drafting rules apply as normal for the event; use sighting discipline so you stay on line when your head comes up. Fueling on the swim is minimal—save your first meaningful intake for the bike while you transition quickly and efficiently.

Think transition flow: exit the swim, rack your bike smoothly, secure helmet and glasses immediately, and get shoes on with minimal wandering time. Before you mount, do a quick safety check (tensioned helmet strap, hydration accessible, and gear set for your first power/effort). Off the line, ride easy for the first few minutes to get blood flow back into your legs and your breathing under control before you start building toward race pace.

You’ll ride 89.7K with 420m of rolling elevation—so it’s a “repeatable effort” bike, not a punch-and-crack course. With wind typical at 6.4 m/s from the west, expect headwinds/crosswinds to affect how hard you need to work on different parts of the course; stay disciplined and use effort (or power) to smooth out surges over the rollers. Aim to take in your full fueling plan consistently: target 90g carbs and 750mg sodium per hour, plus about 650ml fluid per hour, adjusting slightly for thirst and how your stomach feels as the air warms toward ~22°C. Keep hydration regular through the middle of the ride rather than chasing fluids late—moderate heat plus wind can still leave you dry if you only sip when you feel behind.

Plan your T2 so your legs feel “ready,” not flat. When you rack your bike gear and start running, expect your first steps to feel heavy; keep the first 800–1,000m controlled, focusing on cadence and relaxed shoulders. Mentally set a pacing restraint early so you can run the flat/fast profile hard once your rhythm locks in. Transition logistics: shoes on, cap/any eyewear stable, and start running without stopping to re-tie—then re-set your stride after you’re moving.

The run is 21.1K with only 35m of total gain, so the course is built for speed—but off the rolling bike, the biggest risk is starting too fast. With typical temperatures trending from cool conditions toward moderate heat (14.4–22°C), maintain even effort and avoid letting early crowd energy spike your pace. Keep your intake frequent (follow the fueling plan your race-day guide provides); even on a flatter course, heat and wind can still drive dehydration and gut stress. Use the flat sections to lock in rhythm—shorter, quicker steps when you feel fatigue, and full exhale on the effort rather than tightening your grip and shoulders.
