Martti Vainio, Finnish runner

Martti Olavi Vainio is a Finnish former long-distance runner. In Finland he is recognized as the last of the great runners of the famous "V-line", the previous ones being Juha Väätäinen, Lasse Virén, and Pekka Vasala. Each of them won at least one gold medal either at the Summer Olympics or the European Athletics Championships in the 1970s. Vainio's accomplishments are tarnished though, for testing positive for PEDs on at least two occasions. One of those events was the 1984 Olympic Games where he was disqualified and stripped of his medal and later suspended from sport.
