The Outdoor Trophy is a summer extreme-sports relay in Austria's Bregenzerwald region. Teams divide tasks across four distinct disciplines: mountain running, paragliding, whitewater kayaking, and mountain biking. The event has taken place annually since 2002 and is presented by its organizers as an unofficial world championship for outdoor sports.
The format is straightforward to grasp and demanding to complete: each team requires specialists capable of navigating steep terrain, air, swift water, and bike trails within the same race day. It attracts dedicated extreme athletes over casual participants, and the organizer characterizes it as one of the most challenging relay competitions globally. Competition director Chris Alge also highlights a practical aspect of the event's culture: teams frequently utilize the online athlete exchange to recruit needed teammates before registration deadlines.
