The use of Korketrekkeren for tobogganing created a conflict with the local residents?especially at the guest house in Sverdrupstuen, which was often blocked on Sundays. There was also a conflict between cross-country skiing and tobogganing, as both groups wanted priority on the road. Akeforeningen proposed holding a tournament in 1921, but this was rejected by the municipal council. However, an auto race was held on the track that year. Permission for the sleighing race was given the following season, resulting in regular tournaments. Construction of Heftyebakken took place in 1930. The track was constructed between Frogerseteren to Svendstuen, including a concrete curve which allowed it to connect to Korketrekkeren. Heftyebakken had a poor profile as it was not steep enough in the lower areas. In 1950, Heftyebakken was converted to a skiing trail and Korketrekkeren became a pure tobogganing trail.[3]
