The Duathlon du NAVECO is a nature duathlon held in Betschdorf, a village in France's Grand Est region. It takes place in late March, offering the standard run-bike-run format in short-distance categories, including XS and S races, alongside children's and junior events. Participation is individual, and the limited field size makes it a local event where early registration is advised.
NAVECO Betschdorf, the local triathlon club, manages the event and is affiliated with the Grand Est regional league of the French Triathlon Federation. The race holds significance competitively, serving as the Grand Est Duathlon Championship for adults, teams, and juniors. It also provides a pathway for athletes toward higher-level French junior and Division 3 competitions. For younger participants, it acts as a qualifier for the Regional Junior Challenge, meaning the participants range from newcomers and club athletes to juniors seeking selection and adults aiming for a regional title.
