Race Info
The 3 Country Marathon starts on the harbor promenade of Lindau, an island town on Lake Constance in Bavaria, Germany, and finishes at the lake stage stadium in Bregenz, Austria. The course runs along the lakeshore and loops through St. Margrethen, Switzerland, crossing three national borders over 42.195 km. First held in 2001 and now sponsored by Sparkasse, the race has grown into one of the region's largest marathons, with a companion half marathon, quarter marathon and relay drawing more than 11,000 combined participants in recent years.
