Korketrekken Bob Run

The one temporary venue used at the Olympic Winter Games Oslo 1952 was the Korketrekken (“Corkscrew”) Bob Run on Frognerseteren hill. Fashioned from snow and water, the run was 1.5km long and comprised 13 curves. It melted in the summer after the Games and was not rebuilt. A 2km public sledge run was later constructed next to the track outline and remains popular with both tourists and locals. The track opens as soon as there is enough snow. Though it is free to use, visitors must hire a sledge if they do not have their own.

The bob run built for the 1952 Games was temporary because bobsleigh was very much a minority sport in Norway at the time. The country had no permanent track and only made its Olympic debut in the discipline at St Moritz 1948. Construction costs were thus reduced, and the risk of the run being underused after the Games averted.
