IRONMAN 70.3 Luxembourg offers a unique triathlon experience spanning three countries in the heart of Europe. Participants swim in the river Moselle in Germany, ride along the rolling Moselle valley through Luxembourg and France past vineyards and historic monuments, and finish with a flat run along the riverbanks in the host city of Remich, Luxembourg.
The event features individual entry as well as relay team options. Early registrants can take advantage of the Flex90 offer, which provides entry flexibility including fee-free transfer and partial refund options when registering within the first 90 days of opening.
An upgraded race experience powered by NIRVANA is also available, offering premium support services such as priority check-in, bike mechanic tune-ups, and dedicated race-day transportation.
The transition area is located on a meadow outside of the City of Remich, requiring a 400 m run from the swim exit. Athletes collect their BLUE BIKE BAG from the bag rack, change in designated areas, and repack swim gear into the bag before proceeding to their bike.
Athletes dismount and rack their bike at their designated spot in T2. After picking up the RED RUN BAG, athletes change into running clothes, place all cycling gear into the bag, hang it back on the rack, and head out on the run course.
Athletes who register within the first 90 days receive Flex90 benefits, including fee-free transfers and partial refund options if plans change.
