[2] He also triumphed at that year's International University Games, scoring 3979 points to secure gold ahead of Latvia's Jānis Dimza.

[3] Tolamo's world record was broken the following year by compatriot javelin thrower Matti Sippala;[2] however, with modern scoring tables Tolamo's score would have remained the record, and it eventually re-emerged as a national pentathlon best, only broken in 2007.

[3] He broke his own national long jump record in September 1934, in another dual meet (between Finland and Germany); he jumped 7.51 m and defeated both Wilhelm Leichum, who had won the European championship the previous week, and future Olympic silver medalist Luz Long.
