Hellström was a prolific sports administrator, who founded his first sports club, IF Sleipner Stockholm, in 1897, aged 17. In 1901 he launched the first cross-country race in Sweden. In 1912 Hellström became Secretary-General of the Organizing Committee of the Stockholm Olympics; he was also a founding member of the International Association of Athletics Federations (IAAF), becoming its first Secretary-General from 1913 to 1914.
