Career
At the 1928 Summer Olympics in Amsterdam he competed in the pole vault and decathlon, finishing in the top ten in both events. In July 1928, ahead of the Olympics, he jumped 3.92 m in Stockholm, his first Swedish record. At the Olympics Lindblad took part in both the pole vault and the decathlon.
He was the best European in the pole vault, clearing 3.90 m and placing seventh.
In the decathlon he was ninth, scoring 7071.425 points (5906 with modern scoring tables). After returning home he improved his Swedish pole vault record to 4.00 m, the first Swede and only the third European (after Charles Hoff and Henry Petersen) to vault four metres or more.
He set his eventual personal best (413 m) in winning the 1931 Finnkampen, holding the Swedish record until Bo Ljungberg cleared 4.15 m four years later.
