Badges
Once earned, a badge becomes a permanent part of a rider’s record and cannot be lost. This is an overview of all badges obtained by Jan de Groot. Certain badges may supersede others within the same category; when a higher-class badge is obtained, it replaces the lower one in the rider’s visible collection.
