The highlight of his career came in 1972, when he equalled the world record of 68.40 metres at the Dagens Nyheter games in Stockholm and, later that season, won a bronze medal at the 1972 Summer Olympics in Munich.

He readily changed his opinions on various matters, and represented around a dozen athletics teams, including his own IK Diskus.

Bruch was a solid athlete, but failed to achieve the greatest success possible in major international events.

[5][6] His autobiography Gladiatorns kamp (The Gladiator's Battle) was printed in 1990, and an anthology of his poetry, Själ och kropp: Dikter (Body and Soul: Poems), has also been published.

At the Swedish Championships in Västerås in 1985, Bruch was involved in a dispute with Anders Borgström, the team captain at the time.
