Miroslav Vraštil Sr.

Vraštil is married with five children. His two eldest children, Miroslav Vraštil Jr. and a daughter, are also competitive rowers. His son has competed at the 2012 and 2016 Summer Olympics for the Czech Republic.

After he finished his competitive rowing career, he worked as a rowing coach for five years. When Czechoslovakia became the Czech Republic in 1993, Vraštil became a school teacher.

In 1988, Vraštil entered his first triathlon and of 130 competitors, he was almost last. He had lost his fitness after ten years with little exercise. He became more competitive in the event and in 2010, he embarked on the attempt to beat the world record of finishing more than 20 Ironman Triathlon races within one year. He managed the feat and completed 22 races during 2010.

A tumour in his right leg was diagnosed later in 1981. His doctors wanted to amputate the leg at the groin, but he insisted that the tumour be removed instead. Three months after the operation, the tumour stopped growing. He did not undertake any training for six months, but started again in the spring of 1982. Later that year, he came fourth in the 1982 World Rowing Championships, where he competed in the men's four. In the following year, he competed with the men's four at the 1983 World Rowing Championships in Duisburg, Germany, where the team came fifth. His fourth Olympic appearance was prevented through the 1984 Summer Olympics boycott.

In the 1978 World Rowing Championships in New Zealand, he changed to the men's four boat and the team came fifth. At the 1980 Summer Olympics in Moscow, he was the stroke of the coxless pair, and he came fifth with Miroslav Knapek. In the 1981 World Rowing Championships in Germany, he was fourth in the men's four event.

In the 1972 Summer Olympics in Munich, Germany, he competed in the men's eight with the team coming tenth. At the 1973 European Rowing Championships in Moscow, he won a silver medal in the men's eight competition. In the 1975 World Rowing Championships, he came fourth with the men's eight. He competed in Montreal in the 1976 Summer Olympics in the men's eight, where the team came sixth.

Miroslav Vraštil (Czech pronunciation: [ˈmɪroslav ˈvraʃcɪl]; born 31 July 1951) is a retired Czechoslovakian rower and triple Olympian. His son, Miroslav Vraštil Jr., is also an Olympic rower.
