The H.U. Nepper Kinder-Cross Duathlon, organized by TSG Waldenburg, is a run-bike-run event for children in Waldenburg, Baden-Württemberg. It takes place in July, with registration closing on July 10. This 20th edition maintains a format focused on young athletes.
Participants compete in four school-age categories: Schüler D (ages 6-7), Schüler C (8-9), Schüler B (10-11), and Schüler A (12-13). Each category has a limit of approximately 30 participants. The distances are brief: a 0.40 km run, a 2.00 km bike ride, and a final run of 0.45 km for most, though the youngest children complete a 0.15 km final run.
