ARDOC, also known as OLG St. Vith, is an orienteering club that brings together members to take part in the sport and related activities in Belgium. The club shares information about orienteering, its organization, maps, events, photo albums and useful links, and provides registered members with access to club-only content. Its calendar features regular ARDOC training sessions alongside evening orienteering, military orienteering events and seasonal activities such as a Christmas sprint.

ARDOC members participate in competitions across a range of formats, including sprint, middle-distance and long-distance orienteering, as well as mountain bike orienteering. The club reports on Belgian championships, international competitions and member achievements, and supports shared club outings to multi-day events. These gatherings combine racing with opportunities for members to spend time together. ARDOC also contributes to the organization of future events, including the 2027 Three Days of Belgium in partnership with OLVE. Through training, competition and community activities, the club offers ways for participants to develop their navigation skills and enjoy orienteering together.
