IRONMAN 70.3 Luxembourg 2027
Three countries in one race. Swim in the Moselle from the German bank, ride through Luxembourg and France, and finish on the riverside in Remich.
47 weeks to race day: base season
Plenty of runway. This far out, the win is a boring, consistent base rhythm: aerobic volume, strength, technique. The structured block starts closer in; what you do now decides how high it can climb.
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.
Build my complete road.
Commit to the date and the work gets a shape: your countdown starts, the emails arrive in step with your build, and the app anchors a recovery-led block so the final week lands exactly on race day.
One confirmation email, then the road begins. Registering for the race itself stays with the organiser.
“You swim in Germany, ride through Luxembourg and France, and finish back in Luxembourg. Three countries in one race is a very good story for the price of one entry.”
The race
The course
No course maps for this race. IRONMAN publishes no downloadable route for any leg of this race, so there is nothing to draw a course map from. Everything below comes from the official course page, checked on the date at the foot of this section.
One loop of the Moselle, starting from the Luxembourg bank and crossing to the German side. A river swim with a low current, which is rare at this distance and means sighting matters more than usual.
One rolling loop through the vineyards and small towns of the Moselle valley, passing the Schengen Monument. Rolling rather than flat, so it rewards riding the small rises steadily rather than attacking them.
Flat and fast along the riverbank through Remich, with the crowd close in on both sides. The official page does not state a lap count for this leg.
Not yet confirmed for this edition: run lap count, bike elevation gain, cut-off times, aid station spacing, course maps (no official GPX published). We publish these only once they are on the official course page, so check there before you pace off anything here.
Course details verified against the official IRONMAN 70.3 Luxembourg course page on 13 August 2026. Courses change; the official page is always the last word.
