IRONMAN 70.3 Duisburg 2026
A calm regatta course swim, flat fast closed roads through the Ruhr, and a flat run in the sportpark. A controlled, low-variable 70.3.
0 weeks to race day: the sharpening window
A full build no longer fits, but a sharp one does. This close in, the job is specificity and freshness: race-pace touches, open-water or brick rehearsal, and a taper your nervous system actually absorbs. No heroics; arrive fresh.
Building for this one? 70.3 training plan covers the sessions, the weekly shape and how the block is paced. The R.A.C.E. Framework explains why it is built that way.
“A rowing course swim and flat closed roads. Almost no variables, which makes it a very good place to find out what your training is actually worth.”
The race
The course
IRONMAN publishes no route file for this leg, so there is no course map to draw from.
The regatta course at Sportpark Duisburg, opened in 1935 and a venue for canoe and rowing world championships. Lane-straight, clean and easy to sight, which makes it one of the least stressful swims on the calendar.
Two loops over the historic Bridge of Solidarity and along the Rhine towards Moers. Flat and fast, so a realistic personal best course, and the bridge is the only thing resembling a climb.
Three laps along the regatta course through the park. Voted third best 70.3 run in Europe by the athletes who did it, which usually means flat, shaded and well supported.
