IRONMAN Rockford - Illinois
Rockford's 70.3 is a straightforward midwestern race: 1,900 m in the Rock River, 90 km on rural Illinois roads, and 21.1 km on the trail network through the middle of town.
There is no signature climb and no famous landmark. What it has instead is quiet farm roads with long sightlines, a river swim, and a shaded trail run, which together make it a sensible choice if you want a fast honest half without transatlantic travel or altitude.
The Rock River is the part to prepare for specifically. Its temperature swings with the preceding weeks of rain, which makes the wetsuit call unpredictable, and moving water means your line matters more than your stroke rate. Practise sighting against a current before you get there.
Mid-June in northern Illinois is warm and often humid, and the farm-road sections have nothing at all to break a crosswind. The trail run at least gives you tree cover for stretches, which is more than most flat halves offer in June.
