In 1930 Lindblad won both the Swedish and British pole vault championships, a feat he repeated in 1931. He set his eventual personal best (4.13 m) in winning the 1931 Finnkampen, holding the Swedish record until Bo Ljungberg cleared 4.15 m four years later. Lindblad won further Swedish titles in 1933, 1936 and 1937 and placed seventh at the inaugural European Championships in 1934.
