IRONMAN 70.3 Emilia Romagna

Sunday, 20 September 2026

A flat/fast 70.3 built around controlled effort—smooth 1.9 km freshwater swim, a fast 90 km bike, then a steady 21.1 km run where you finish strong on moderate heat and a light SE breeze.

T1 — swim to bike

In T1, organize your gear before you go in: glasses/hat if you use them, helmet on correctly, shoes laced, and a smooth mount. Keep the first pedal strokes controlled—grab water if you need it, breathe, and focus on staying aerodynamic and stable rather than racing off the line. Since the bike is flat/fast (90 km with 245 m gain), your opening goal is to build toward your target power/effort quickly without blowing up before the long middle.

During the bike

The 90 km is flat/fast with only 245 m of elevation gain, so the course rewards steady power and disciplined aerodynamics. With a light SE wind at 4.8 m/s, expect some subtle headwind/tailwind effects—if you have any stretches directly into it, don’t surge; let your effort stay consistent and use a smooth cadence to hold speed. Fuel and hydrate to your race target: 90 g carbs per hour plus 750 mg sodium per hour with about 650 ml fluid per hour, starting early enough that you’re never “behind” during the middle of the ride. Take fluids on a steady schedule (not in one big gulp) and keep your sodium coming regularly so you stay even as the day warms (air temp range 16.4–24.2°C).

Closing notes

On a flat/fast course, your win is consistency—hold steady effort into the wind and fuel/hydrate from early to avoid late-race drop-off.
