Le Defi Mark Ten International was one of the most prestigious strongman contest in the world in the 1980s and early 1990s. Staged in Quebec, Canada, it was begun as a tribute to Louis Cyr and was notable for the quality of the strength athletes it attracted, which included a number of winners of the World's Strongest Man competition, including Jón Páll Sigmarsson, Bill Kazmaier and Magnús Ver Magnússon.
Live strength athletics competitions had begun in the late 1970s as a distinct set of disciplines from other strength related sports such as powerlifting or Highland Games. However, the associations of the new phenomena with its sporting forebears resulted in certain countries being at the vanguard of such competitions. One such country with a deep rooted past in strongman competition was Canada, and in particular Quebec, referred to as a "cradle of strongmen". In 1984 Jean-Claude Arsenault began to promote a competition named after the most famous of Quebec's strongmen of the past, Louis Cyr. The Louis Cyr Tournament was quickly a success and gained the sponsorship of a cigarette company resulting in its change of name to Defi Mark Ten.
The first outing of the competition caused some newspapers to claim that "Nationalism marred contest" citing the fact that Quebec was painted on the backdrop to the competition deliberately separate from Canada and grouped with France. Despite this, there was noted by the same newspaper an impressive camaraderie amongst the athletes.
The event attracted the very top strength athletes in the world. Amongst these names were Bill Kazmaier, Magnus Ver Magnusson and Jon Pall Sigmarsson. The Canadian Tom Magee was the winner of the first three tournaments and the giant Mark Higgins has been cited as the final winner before the sponsorship ran out in 1992. A final contest was reportedly held two years later, with Raimundas Zenkevicius claiming that title although sources differ. In 2008 a competition called Fortissimus, founded by Paul Ohl, was staged in Canada which also claimed to be a tribute to the great Louis Cyr and was thus seen as the natural successor to the Defi Mark Ten International.
