In 1966 Swedish cross-country skier Ingvar Sandström made his début at the World Nordic Ski Championships, finishing fourth in both the 30 kilometres and the 4 × 10 kilometres relay events. Two years later Sandström was selected to compete in the former event at the Grenoble Olympics, where he finished 21st overall. He returned to the World Championships in 1970, where he was part of the quartet that won bronze in the 4 × 10 kilometres relay. Sandström remained part of the national team for a few more years, including being named as an alternate for the 1972 Sapporo Olympics, although he did not participate at the Games.
