Bundesleistungszentrum Kienbaum, Olympic training center in Grünheide, Germany

The Bundesleistungszentrum Kienbaum is a national sports training center in Grünheide (Mark), a town east of Berlin, with facilities covering track and field, canoeing, gymnastics, volleyball, and triathlon among other sports. The grounds bring together indoor halls, outdoor areas, on-site accommodation, and medical support all in one place.

The site was originally set up in 1949 as a recreation park and was converted into a training center for top athletes in 1952. Over the following decades it developed into one of the main places for training German athletes at the highest level.

The name Kienbaum has stood for centralized, cross-sport training since the GDR era, when the Deutscher Turn- und Sportbund ran the site from 1952 to 1990. Today the campus is used by national teams and sports federations for training camps, and the roughly 15 seminar rooms and a dining hall seating about 300 people host courses and meetings alongside the sport.

The site is a training centre, not a visitor attraction, so access is normally limited to athletes and officials. It lies about 35 km east of Berlin in the Kienbaum district of Grünheide, and the 60-hectare grounds are easiest to reach by car. The nearby Liebenberger See holds a measured 1000 m and 300 m canoe course and a marked triathlon route.

The underground altitude-training facility was built in 1966 and expanded between 1977 and 1979; its existence was only made public in early 1990. A smouldering fire in a technical room in February 2022 damaged the sports museum and the historic low-pressure chamber with smoke and soot.
