Career
His first major medal came at the 1978 European Athletics Championships, where he anchored the Polish 4×100 metres relay team of Zenon Nowosz, Zenon Licznerski and Leszek Dunecki to the gold medal in the event. He competed for Poland in the 1980 Summer Olympics held in Moscow, Soviet Union in the 100 and 200 he reached both finals finishing seventh in both sprints. His fastest time for the 100 m was 10.00 seconds, recorded in 1984 in Warsaw with wind on the maximum allowable limit of 2.0 m/son
This was the European record for the event until Linford Christie ran 9.97 sec at the 1988 Seoul Olympics.
Although Woronin"s official timing read as 10.00 seconds, this was rounded up from 9.992 seconds – some claim this represents the first time that a Caucasian (and a European) broke the 10-second barrier in this event. He is one of only eight individuals not of West African descent to run 100 metres in 10.00 s or less – the others being Koji Ito of Japan (1000 in 1998), Australian Patrick Johnson (993 in 2003), Namibian Frankie Fredericks (995 in 1991), Zimbabwean Ngonidzashe Makusha (997 in 2011) Frenchman Christophe Lemaitre (992 in 2011), who is the first person of European descent to officially break the barrier, Zhang Peimeng (1000 in 2013) and Su Bingtian (999 in 2015), both of China.
Woronin"s personal best in the 200 m was 20.49.
