1973 Universiade, Moscow: Athletics gold in the 400m. 1977 Universiade, Sofia: Gold in the 800m (1:43.44, world record)

This huge and hugely talented Cuban athlete, who was originally steered towards a basketball career, announced his international potential in track and field as he won the 400m title at the 1973 Universiade in Moscow.

Four years later, he secured another Universiade gold in Sofia - this time over 800m.

In between these two victories, the 6ft 2in athlete from Santiago de Cuba produced one of the all-time great Olympic performances at the 1976 Montreal Games as he became the first since Paul Pilgrim at the 1906 Intercalated Olympics to complete the men’s 400m and 800m double.

Juantorena had only taken up two-lap running the previous year, but he led the field in the 800m final for most of the race before clocking a world record time of 1:43.47. Three days later, he added the Olympic title over the single lap in a low-altitude world record of 44.26.

His Universiade career ended with a flourish in Sofia as he improved his own world 800m record to 1:43.44.
