IRONMAN 70.3 Ruidoso New Mexico

Arrive early enough to settle your breathing and get calm in the water before you start. Line up based on your expected swim pace—don’t overreach in the first minutes, especially with variable freshwater temperature. Once the gun goes, focus on smooth technique and controlled effort for the first few minutes: settle your rhythm, keep your head position consistent, and avoid sprinting over the first buoy interval.

You’ll swim 2128 m in freshwater, and the water temperature can vary, so treat the opening as a “warm-up in motion.” Keep your effort steady rather than chasing early positions—drafting may be available in spots, but your job is to swim efficiently and arrive at T1 with legs as intact as possible. With a hot race environment, you’ll likely feel tighter sooner; drink-like hydration starts now in your timing—think “don’t delay” when you transition, and avoid overheating on the deck. Fuel during the swim is not the focus; the goal is to get out clean, dry off as much as you can, and be ready to take in fluids immediately on the bike.

Use the swim-to-bike transition to reduce wasted time and friction: get organized before you stand up, secure your gear calmly, and settle your position before you commit to power. After mounting, give your first minute a “build” feel—bring cadence up smoothly, then find your target effort and stay aerodynamic and relaxed. The rolling profile and ~695 m of gain mean you should plan to ride steady on climbs and avoid spiking on any short rises; your first focus is stability, not speed.

You’ll cover 89.9 km on a rolling course with about 695 m of elevation gain, so expect repeated changes in power demand. Wind is from the S around 3.6 m/s, which can shift your feel and stability—stay consistent in your setup and don’t yank power when gusts hit. Heat is a factor, so your fueling and drinking should start early and remain continuous; your target is 90 g carbs, 1000 mg sodium, and 800 ml fluid per hour. Use the aid stations/scheduled bottle strategy to keep your numbers on track rather than “catching up” later, especially before the bigger stretches of climbing. Aim for smooth, repeatable effort over the rollers, and protect your run legs by not turning every rise into an all-out push.

During T2 (bike→run), expect your legs to feel a bit disconnected at first because of the ~89.9 km bike and the rolling fatigue pattern. Get your first steps under control: quick cadence focus, tall posture, and don’t chase pace immediately—let your breathing come online. If you can, start the run with the same fueling plan you used on the bike, and use the first aid areas to lock into your fluid and electrolyte rhythm.

You’ll run 21.1 km on a rolling profile with about 134 m of gain, meaning there will be frequent small transitions in effort. With hot conditions and a breezier environment (wind from the S), hydration management becomes the performance limiter—your job is to keep cooling and fueling steady instead of spiking effort on the downhills. Keep your carbs and sodium intake on target at roughly 90 g carbs and 1000 mg sodium per hour, and match fluid to what you can actually absorb comfortably (your overall target is 800 ml per hour). Use each aid station as a checkpoint: take what you need, even if you don’t feel thirsty yet, and use water to stay cool. As the run progresses, resist the urge to “save it for the end” by banking too hard early; on rolling courses, the best approach is controlled surges only when they’re sustainable for your breathing and gut.
